88 Ford Bronco Bed Rust & ideas

First off, I did a search on this forum (I think) and also via Google, and I didn't see anything with pictures or with the same thoughts of repairing said rust. This isn't a build thread- just an idea thread. When I start making headway on the bronco, than maybe I'll start a build thread.

So - rust has separated the bed right at the outside edge of the frame. When I drop the tailgate, the sides move up.

So, if I can figure out how to post the pictures, I'm considering putting c-channel or tubing between the body mounts and bed, all the way to the inside of the exterior panels, and take supports up to the bed rails. This may be a temporary fix or it may be a permanent fix. And than figure out a way to tack the exterior skin to my frame.

My long term goal is to build a locking toolbox or 2 or 3 in the bed - so I figured...why not do both? Instead of replacing the floor/bed steel, I could build boxes and maybe line the boxes with 1/2" foam insulation to provide some sound/weather proofing.


As long as my framing is on top of the body mounts, I should be alright...correct?

88 Ford Bronco Bed Rust & ideas

My bed was trashed but more toward the center and passenger compartment.I replaced the bed and sill but the area beyond the seams were not that chewed up.

Hope this works...

I appreciate the google link! That has definitely given me some ideas.

I don't know if I said it before, but I plan on pulling the truck into my work's shop this evening and taking a look at it this weekend. I should be able to make a plan from there.

I do have a friend that has a full size pickup truck with an 8' bed that he was willing to give me. That was his plan anyhow. I just don't know how far I want to get into body paneling, at least at this point.


I'll definitely have more photos after this weekend.

I believe the majority of the truck is in fairly decent condition.

Cool- feel free to cruise Project Alpha Bronco for any ideas. The boy and I have been putting this thing together for a couple years. Not much left but to align panels and paint it. Then we will re assemble the interior.

WOW treehick, Your 88 is rusted just like my 88! Right where the rear tires fling all that road shit to freeze and bake! My rear wheel wells are rusted thru the outer panels on top also. Good thing the stainless trim strip is still there. Not so noticeable. (right!) A few years ago I bought a can of "Eastwood Rust Encapsulator" in Satin Black. I went to the do it yourself car wash and hosed the bageeziz out of the shitty areas. I let it dry on the drive back home and taped off anything I didn't want overspray on and soaked it down good with the Eastwood stuff. Believe it or not, that shit stopped the rust from growing. I also did the bottom/inside of the tailgate. It stopped that rust also. Not sure where I'm going with this Bronco now, but I thought I'd just pass this along if it could help. Sounds like you are thinking of replacing the whole rear end. Whatever you decide, good luck...

Don't know about that stuff, but all of Eastwoods stuff is the shit! At least it's worked for me...

OH YEA! They got a buttload of vids on Youtube!

that thing is like colonial sanders secret recipy,extra crispy

I bet you will find the rear crossmember is non existant,at least on the ends
I'm sure it could be fixed,but it will be a shit load of work and a new tub would be easier for sure
I ended up getting a replacement from California with zero rust as the saltbelt here pretty much ate the entire structure under my bronco

check the other body mount crossmembers,and lower b post
yours looks a little worse than my current beater 78,but hard to tell exactly from limited pics

recommend before you do anything to pull entire interior and have a good look at the tub
structural rust sucks ass to repair



I made up a rear crossmember from 2x6 tubing and tied it unto the inner quarter with 2x4 tubing running up the insides to under the cap mount rail so the support is now on the rail as well as the inner quarter
before I needed a ratchet strap to hold the side on,now I would probably pull truck sideways using rear corner of bed

A tub is much easier to replace than all the channels, support, mounts and roof.

I'm really interested to see what the floors and B pillars looks like with the interior pulled.

That's why it's a project right?!

Thank you so much trustyrusty for the dimensional tubing. I was just wondering that because my rear most cross member is rotted. And I have a similar idea to fix the issue as you described. Building a bed frame to replace the existing.

My photo album is updated to reflect my findings.

My 91 rear rail ends were soft even with a realitively clean body, so were my roof pillars. Here is an overview of the work I have done so far if you want to see everything opened up and stripped clean.
The 445 FEs start from scratch build.

A) Where would I find an entire tub rust free at a decent price?

B) It appears that the roof and majority of the sheet metal from above the rocker panels are fine.

How would the tub tie-in be easier compared to, as trustyrusty stated, remove the floor, build a frame on top fo the body mounts which appear to be solid, and build a floor off of that?

My coworker, who fixes everything the first time, told me that I could just take some 1" squared structural (1/4" thick) tubing and build a frame for the floor. From his stories, it sounds like he knows what he's doing. He said - build the frame, get some steel for flooring, weld or pop-rivet angle pieces from the floor to the side wall, then paint everything.

However, from your posts, it appears my metal list should be something like:

6' 2x6
32' 2x4
16 gauge steel sheets - would probably get two 4x8 sheets

https://goo.gl/photos/KVguKs8aM4wWZuYy9 (picture wouldn't upload)


I may cut out the wheel wells and do weld a structure similar to /--\ and add some steel later inside the wheel well for curvature, if I think it's necessary.

johnnyk8 - what size tubing did you use for your rear cross member?

What is the space between the floor and the bottom of the solid most part of the bed rail?

All the links so far together:

Body tubs would have to be sourced out south, I went to Arkansas and picked up a clean Texas tub that needed quarters and some miner patching for my 78. Replacing wells and floor in the rear I would snag a pickup bed, it would be a lot of work but it would be a realitively close match. The jambs are available for the tailgate area aftermarket. The main areas that are not available are the support channels, area behind the front seats and firewall sections.

i'm having the same issue you describe where the body panels move when the tailgate is lowered. I'm thinking about just caging the bronco and having custom sheetmetal tie the bedsides to the cage which will in turn tie into the floor.

Came from Subaru, now in a Bronco. No matter what, it's better on all fours.
