I came across an alternator bracket on 67-72 generation truck and it had an engineering number of C80E-10145-A. I have come across numerous
C8AE-10145-A ones but none with the C80E. Would like to know more about the application of the brackets--model/years and the like if possible.

One thing is for sure--the C80E bracket is larger.

 

Did the truck have air conditioning?
Here's an ad claiming F100/F250. Don't know why an F350 would be different. I'll check mine.

I don't recall

 

These do fit some cars also but on Bumps it's basically with or without A/C is the difference.

C8AZ10145A....F100/350...360/390,without smog pump,without factory or add-on A/C, with 38,42,45,55 amp alternators

1970-72:
C8AZ-A:
F100/350 360/390,without A/C...38,42,55 amp alt.
C8OZ-A:
F100/350.60/390 with A/C, before ser #M20,001..with 55 amp alternator.

 

Thanks a bunch.

It appears to me based on my junkyard hunting, the C8OZ is much more rare (at least in the trucks that I have found).

 

Correct-a-mundo Sam. Most of out generation of Ford trucks were without A/C and had the smaller alternators.
