Finally got to start my thread here is my 1978 Bronco. I've had the truck for 25 years. I’ve gone through numerous suspension type and motors. Now the truck is at a maintenance and tuning stage.

What are the details on the suspension and bodywork? I'm really liking those front fenders!
All the body is homemade.

Did my molds since getting thing through the border was really to expensive!

I would of like going the easy way and buying Autofab parts but at the time I was in college and couldn’t afford them.

The first piece that I did was my drop center hood. An 81 Bronco center section matted to the 1978 side.

awesome build. I especially like the little details.
For example the mud flaps to keep crap out of the rear springs on the coil overs. Great cost effective idea
Also like the cutout for the driveshaft to droop further on the front end. Lot of people overlook this on the 78/79's
Shows to me how much this has been actually used. Like I said cool stuff overall. Keep sharing.

Very nice, can i see more of the front bumper,
Here are pictures of when I fab the bumper. I wanted protection for the Bottom of the rad. the Bottom part is also attached to the front cross member. Made my winch plate to be as close as possible to keep a good departure angle.

Sway bar is mounted well too.
Really only way to do it on these without killing ground clearance

Found a couple of picture of the rear end when I cut the bedsides.

Gives me about 20 inches of travel with 14 in the front.

With the swaybars, the trucks rides great at high speed with just enough bodyroll to send the rear in the cuves!

Winter project will be to finish the front diff. I’m keeping the stock Dana 44 since I have a bunch of them and the way the suspension is done I have 7 inches of up travel at almost standard high.

I wanted 14 inches of front travel without raising the truck. This is what the front driveshaft can support with a bit of grinding.

With The 521 BBF, had to make the diff a Jana 54. It’s a Dana 60 in a dana44 case. (low weight high clearance) Did the big brake kit with a hydroboost.

Did some truss to make sure nothing breaks. Did lose a bit of ground clearance with the lower truss. Top truss was out of the question to keep the pumpkin from hitting the BBF oil pan. Everything is tight with only ½ inch of space all over!

Decided to finish the Wheel well protection. Dis a bit a sheet metal to protect the motor and components when going through nasty stuff. I think they came out pretty nice. I still have to find someone with a bead roller to give a bit more strength to the aluminum

I Don't know why I didn't do this years ago.

Hydro brake assist!

Bought a Chevy 2500 hydro system and with minor plate modifications it was one of the easiest mods.

I can lock-up all 4 fours with near 1 inch of brakes travel. Wow finally!

You do have to port your power steering pump. This is the only complicated mod.

Took a couple of pictures of the aluminum plate that I made to get the wright depth.
