I've seen there are two different sizes on the lower bushings ...any way to tell what they are before taking it apart? Thanks

[NOT A TA]

Put a wrench on the bolt head. 3/4" wrench for a 1/2" dia bolt and 13/16" for the 9/16" dia bolt.

the 2 different size bushings on the lowers should be front & rear location on the arm. very easy to tell which is which as they only go in one way. if that is what youre referring to for the different sizes.

the bolts should be the same size for both bushings.

Bushings are sized by the ID. the OD is the same.
Frame holes are 1/ 2" till about end of October, then 9/16"
So if a 3/4" wrench fits the bolt, you have the older, smaller style which is 1/2" . If a 7/8" wrench fits, you have the 9/16" bolt, which is the bigger and most common 73 style.

I think I will Quote myself, from the post JUST BEFORE yours..

Since the Bushings are all the same OUTSIDE DIAMETER
They are sized by the INSIDE Diameter.
IF you really don't understand, order bushings for a 1974 Camaro or Firebird., or 75, or 77.... all the same.

Lol..I do understand
Maybe I miss read the part on the using itself being the same size..thanks
