Hey guys, which AC/PS bracket do i use when doing an s4 13b swap into my 85 FB, using FB PS and AC

the FB one? the FC one bolts to the engine too, but it puts the ps and ac in different places

thank you sir https://www.nopistons.com/forums/pub...IR#>/smile.gif

for searching purposes:



The 12A PS/AC bracket works on the 13B block..the nuts dont tighten as far down but it works fine.

The 12A Air pump assembly works too

The 12A Bracket for the ALT works too, I used it to mount my S4 Alt



of course all belts remain the same
