ok.. i've got a factory big block factory air truck... 1970... i am pretty sure that the alt is supposed to go on the drivers side.... but i can't find a upper mounting bracket for it... i am using a small block one now with the bolt not even in the slot part but out on the end of the bracket.... was the big block upper bracket the same just longer????? i can't find any info... does anyone have some pics or suggestions...

thanks..

Yes, correct on drivers side mounting and if you are using the oe type lower alt. bracket (short w.p. only) then you will also need to use one of the two oe upper bracket type's pictured below. The top pic is the 68-71 type and the lower pic is of the three piece 72 setup, both setup's use the same lower cast cradle. Cb

ok, great info that looks just like what i have but mine is too short... the alt hits the valve covers.... does the small block one look just like that one???

heres a pic of what i have.... if i move the alt into the ajdusting slot it hits the cover.

The 68-71 BBC top bracket looks very similar to the SBC one you have, but it's longer.

those pics are dead on! I removed all of those parts today to change a leaky mainifold gasket.Easy to remove and replace.There is a strut type bar that mounts from the middle of the drivers side cylinder head to the top of the body bracket for support.
