rear sway bars on full size

can anyone tell me what year cars and models do people use on the rear axle of the full size buicks. my cars are 75 and 73 and I was gonna start looking for rear sway bars

 

The 71-76 full size GM rear bars will all fit. Years ago I found that 74-76 Pontiacs are a good source. Also, if you need lower rear control arms, 94-96 Caprice squad cars had identical measurements but were thicker steel. Hope this helps.

would Riviera be considered full size?

 

What kind of 73 do you have?

 

Yes, The 71-76 Riviera frame was nearly identical to a LeSabre frame. The Riviera wheelbase was 122". The LeSabre was 124".

ive got a 73 electra 4 door I got from a junkyard and parted out a 73 four door that was rotted to hell.

 

I have an Adco aftermarket bar on my 72 Grandville, it works great, thicker than the OEM bar and eliminates the need for specific OEM lower control arms

 

where did you buy the bar from bigpig?

 

9c1 caprice bars are about 1.65" too narrow for big cars..

However, 78-96 b body wagons with bars are correct. Need lca's as well
