I used late 70's early 80's dodge truck shocks. Mostly for length but they are stiffer
This is what I use. Have used Monroe and Gabriel. Usually ask for a '79 1/2 ton.
myself as well. my charger is nothing special, so i don't need special shocks, other than being a tad stiffer.
the car is about a +1 1/2" higher in the rear, so i unhooked the shocks and jacked the car up, letting the rear and springs hang free. i then measured the length between mounting points and added 1" or so to make sure the shock couldn't top out.
i ended up using the monroe heavy duty gas magnum 2. #34832 for 89-93 3/4 ton trucks.
14.750 compressed, 24.375 extended. these have the correct mounting eyes as the B-body. 1/2" steel bushing at the top, and the 11/16" rubber bushing on the bottom.
the imperial shocks are only 22.5 extended, 12.75 compressed.
[specs from my monroe master catalog. i measured the truck shocks i installed, and the measurements were spot on to what the catalog stated.]
