I'll be away from the car for a few days but will look and report back.

Thanks
Now you have my interest
I will go out now and take a picture of my measurement of that AC pulley location precisely with respect to something fixed on the engine so you can compare to what I have within 1/16 inch....if possible.
I will also take same measurement on that crate engine to verify (comparing a 91' to a 95').

There is some play in the bolt holes of the AC when you sit it in position which may contribute to its final position forward or rearward on the engine block.

95' Air Horn - 15/32


95' AC - 1/2


91' Air Horn - 19/32


91' AC - 17/32
