Re: [Amc-list] Early 60s Ramblers tires and wheels, front suspension

[Wrambler242@xxxxxxxxxxx]

I've got used V-8 springs on the front of my American with 3/8" thick 1 5/8" drop plates and radial tuned gas shocks from IIRC was called Gabriels Classic series shock line, now discountinued. Tires are 205/60/15" on repop multipattern early chevy rally wheels in 15x7". No sway bar. It aslo has Prothane urethane bushings in it
   Ride, hmmm it actualy rides very, very close to the same as the 98 Altima GXE we own! The only discernable difference is noise. Hard hits from pot holes or ridges and such in the road produce a noticeable thump or even a bang from time to time. I don't get the feel of the thump in the car! Just the noise! 
    Handling is better then the Altima, maybe I'm prejudiced but I like it a lot. It's tight and it grips. I chicken out before the 205 and 255/60's lose their bite! Steering box is from a 73 Hornet P/S pressured by a Wrangler pump with the lower pressure the Wrangler assist uses. I alwasy wanted the 12-1 box, but this is as good a box as I need! A faster box would likely only get me in to trouble easier.
   What I want to see happen in the suspension is to fine tune the alignment and drop the rear leaves out and rebush them as they are originals. Leaves have double main leaves and second leaves. I did them before I had net access and I could not find new springs.
