Probably a long shot. I have spare alternators, but they're all 7" spread on the mounting ears and since I have switched to serpentine set-up, I need 8 1/4".

I have 1 or 2 I would trade 1 for 1 and I would pay shipping both ways if that's the case.

Here's the ones I have. One has a 3/8" insert in the adjustment bracket ear. I can put an insert in the other cover also if that is desired (it's easier to adjust with only 2 hands that way).

I'm just talking swapping the front cover, so shipping isn't so expensive.

Here's the 7" ones I have.

I found a good deal on a 3G on eBay I can use, but I'll leave this on here in just in case someone would like to do a front cover trade.

I need to look on EBay for an 8.25”. I called around and seems like no yards have them. Thanks for posting your finding.

I found the one above by searching the Lester # 7756-7 and it was only identified by that, so that's why it was probably still there. You might also try 7756, 7752 and 7777. I got Lester # 7756-7 from the 3G info linked below.

I should probably check the 3G thread, but what cars have the 8” spread? I’m going to the junkyard tomorrow and can look for them.
Check the 3G thread on here, but also check this one for a list in the light green chart under the "Choosing an alternator" tab. I would suggest taking a measuring tape. I didn't one time and ended up with another 7" instead of an 8 1/4" one.

Thanks much. I have read both FSB 3G threads and Gary’s thread but I only used the vehicle listing from the 3G thread when I called the yards. I’ll use the part and Lester numbers from Gary’s to improve my search.

It also sounds like the aftermarket has some options. I have a great alternator rebuilder local and trust OEM hardware more, but I won’t be putting 50K miles/year on the Bronco either.

Thanks for providing options I hadn’t realized prior.
