Control arm question??

[gn85]

Hey y'all,

Basic question about control arms. Are the rear up and lower control arms from a Regal the same as the Grand National? I know the Regal had a 7.5 rear and the Grand National had an 8.5 rear. Does that make the arm length/dimension different?? Thanks.

The rears are the same for either rear end. The factory installed arms did have different bushings depending on what suspension level the car had. TR's got harder bushings compared to the softer ones for Grandma's car. Replacement arms all came with the harder bushings.

Thanks for the response Eric. Very informative.

I think the 3rd Gen f-bodies had the same rear lowers also.
