Where to source rear springs for 1966 base model

[larsenj]

My Catalina's rear is sagging a bit, so I spoke with my mechanic and he stated that I need new springs in back. I've done a lot of searching online (Summit, CarID, etc), but I can only find front springs... Does anyone have an idea of where I can source some rear springs? Or, if it's not possible, what other options I might have...?

Thanks in advance!

Jeff

www.amesperf.com has rear springs listed in their large car catalog

I usually call the company that made most of GM's springs back in the day Detroit Eaton Spring. They still have all the prints for the springs they made. They have been very helpful in the past, but I have not called them in about 10 years.

Maybe consider air shocks

I have a slight sag in the rear of my 70 Catalina and am planning to replace the old shocks with air shocks. As your mechanic - it's a much cheaper option...

I have a 67 base model and found front and rear for mine at Summit. They greatly improved the ride height and comfort of the car. Matched them with some Gabriel Guardian shocks from Amazon. I can post the link to the springs I found, might help.
