Backing plate question

[Hammer Head]

Anyone have a diagram (like a CADD/CAD) of an S10 front backing plate & a 3rd gen camaro's front backing plate? I want to know if there's a difference in bolt patterns. If there is, how much.. etc, etc.
I know F body spindles are damn near the same spindle as S truck & G bodies except for the upper mount on the spindle.. because it goes to a strut.
Maybe someone knows the p/n for S truck backing plates & a 3rd gen camaro backing plate.
..any help's appreciated..

[Hammer Head]

:bump:

i found both parts on gmpartsdirect.com but no diagrams or part numbers. tomorrow i am gonna call my buddy at the local gm dealer and see what i can stir up if that will help you any.

...are they the same p/n?

[Big Mack Daddy]

ok Jason, i called my friend at the dealer and he got me the part # for an S-series but he said the camaro was discontinued, the part # for the S-series is 49575

Great, but w/out knowing what the Camaro's p/n is it's kind of pointless having only the S10's p/n in the comparison.. thank you for the effort, though. Maybe I can somehow find the p/n for a 3rd gen camaro.

I still can't find anything on the '82-92 camaro/firebird front disc backing plate. Maybe somebody that has one could do a measurement for me..? I just want to know what the distance is between all 3 holes on the backing plate.
