Identifying a camaro subframe year
 

I know a few people have been having a difficult time identifying the year models of their Camaro subframes that are installed on their truck. I spoke with a Camaro parts dealer and this is what he gave me for identifying your front end. Hope this helps.

FB235 1-5/8
FB295 1-1/4
FB329 1-1/8
FB330 1-5/8
FB331 1-7/8
FB422 1-5/16
FB424 1-5/16

All measurements are rough / approximate done with a measuring tape.

Generally speaking, 70-72 cars used 4-FB329 for the upper and 2-FB235 and 2-FB295 for the lower.
73-74 cars changed the lowers to FB330 and FB331.
75-79 cars used 2-FB329 and 2-FB422 uppers, and 2-FB330 and 2-FB331 lowers.
80-81 cars were the same as 75-79 but the upper rear changed from 2-FB329 to 2-FB424.

Also, look at the outer tie rod ends.
70-74 cars were about 6-5/8 inches long.
75-81 cars were about 9 inches long.

Pardon my ignorance, but these measurements are for what? I am right now trying to find out what year subframe I have so I can order rebuild parts

I went through this a few years ago. On the A Arm bushings is a number and if you can read it and do a cross reference in a Moog book you can find the year of the clip.

Good info but as the guys said you really should have given us a bit of an explanation at the start for the folks who's decoder rings have dead batteries. It took me reading it three times to figure out what you were telling us.

I have the following stamped on my (what I believed to be) Camaro A Arms: K2B9L and K1B9R. Any idea on these? Thanks, Jim

He did that to confuse the NSA.

Another difference is the spindles and rotors :
up till 1978 the outer front spindle is smaller dia .610,(uses A2 bearing)
while 1979-1981 have a larger spindle dia .690(uses A3 bearing)

So if you want to use drop spindles need to know which will work with your rotors.
...ask me how I know that.
