In my 81 wagon i did umi non adjustable rear arms with roto joints on one end with the poly at the other. I also did the umi agustable bracesvand the shock tie brace. You will notice alot better ride. I had full poly armes in car before these. I wont go back to full poly in rear on a car i am holding on to.
if you are considering UMI this guy in Toronto will get them from UMI and ship them to you. He got me lowers and the price was less than I would have paid if I bought them directly.

I have the full Hotchkis set on my 81 coupe but I didnt want to spend big $$ on the wagon. The original arms from the wagon were in fair condition. Not mint. I couldnt see not replacing them with something decent after putting so much work into everything else. The UMIs arent a lot of money, they'll look good under there and Im sure theyre a huge step up from stock.
I still have to get a set of shocks,misc brake parts, seals, maybe bearings, emergency brake cables and a set of backing plates.
Im thinking that would be a good deal if I was that far up North. UMI is in PA. Im on Long Island. Shipping cant be too much and they get $289 for the set.
Just don't make the mistake I made when I ordered the first time from UMI, I clicked on UPS instead of USPS and it cost me $92 to ship $185 in parts.....

I ordered my UMI rear control arms from Summit for my Regal but I went with the upper adjustable with the roto-joint so when I lower the car I can readjust my pinion angle. I feel once you start to deviate from stock it is nice to have some adjustability.
Are these the ones you used?
