Rear shock recomedations

Have a 70 duster with ss springs that are moved inboard car typicaly 60 foots in mid to low 1.40s need rear shocks found one of mine stuck and causeing alot of body roll at least I hope that is what was causeing it. Looking for some input as to what shocks to purchase been thinking mopar performance or calverts but also found some summit adjustable rear shocks that would be the proper length for my application any body have experiance with these? In the future I plan to go with the whole calvert system but right now funds are a little tight and plan on useing ss springs this season but if the calverts are best I coukd bite the bullet and get them now.

I have the Rancho 9000XL shocks and they work great and I only have them set on six

Ive got the Calverts on mine with ss springs . best 60 so far is a 1.41 . The Calverts are the old Rancho 9000 design . (The 9 way) Make sure you call them because there are several different lengths for A body.

I have Rancho(now Calvert)9 way on mine set at 7.
