I've got a 68 conv. with a 383 stroker, m20 trans and 342 12 bolt rear end. Got 5 leaf springs. I'm having a problems with the rear end torquing up and the universal is hitting in the tunnel. Need some traction bars? What kind should I use and where can I get a set? I've been told to use the "plate mounted" what ever that means? Thanks for any advice.
