I dont think all 10 bolts with disc brakes came with 3:45s but some did. From what I know camaro had a 3:42:1 option and the firebird had a 3:45:1 option. What I dont get is why GM had 3:42s and 3:45s. Huge difference their huh.

NOT

I have a 91 or 92 one that came to me with 3.23s and PBR calipers. I rescued it though; it has 3.73s now.

No 10-bolts came with 3.45s at all. 10-bolts sometimes come with a 3.42 (12 and 41), and 9-bolts came with a 3.45 (11 and 38).
