Matching Torsion Bars, Leaf Springs and Shock Absorbers

I'll put in my 2 cents for Bilsteins for this application. With the "non-road race" torsion bars and rear springs. I think that investing a little in shocks that are a cut above stock is a good move. They will provide more control with those springs. I have 3 1970 Darts, on one I bought the Bilsteins and I was surprised at the difference.

By the way those "spaghetti" .89 torsion bars are what Chrysler engineers (you know, the ones that designed the rest of his car) specified for a Dart with a big block. I think they will do just fine.

Yeah for 5" wide bias-ply tires... they'll work but after feeling the difference I'd never run below a 1" bar in anything unless it was a drag car that needed weight transfer. I don't think the OP should get rid of his if he already spent the money and put them in the car but if he might ever consider upgrading they're completely worth it, totally transforms an old Mopar for the better with no negative effects.
