How to identify 2nd gen Control Arms

[73camaroz28]

I bought a 1973 Camaro Pro Street with a big block, (was a full time drag car)
Putting back on street doing a major clean up.

I cant seem to find bushings and ball joints to fit, made mistake throwing old ones away before new ones.

These arms appear longer than stock,

How do I tell what year control arms I have?
I called the old owner he thought they came off a big block truck?

May be cheaper and easier to buy these. http://www.speedwaymotors.com/1970-94-G ... 59017.html
