Can custom front end alignments be had?

Torsion bars are pretty close to 7/8" depending on where I put the calipers.

This is a pic of the shock through the mirror. It's a Deluxe HD. What more could a boy want?

I did jump on each corner to check rebound and found all four corners firm.

7/8" is closest to the .87" stock torsion bar, they came on 340 cars and 318 cars with A/C. They're from a later car, I don't think they would have been found on a '64 normally and definitely not with a /6, so they were probably added as an upgrade with the BBP front brakes, tubular UCA's etc. Wheel rate on those is 109 lb/in, which is better than stock for a '64 but still probably about half the rate they should be with a decent radial tire.

Ride height will need to be stock with those torsion bars to keep them from hammering the bump stops all the time. Even at the stock ride height you'll still be using the bump stops with those bars, they did right from the factory. Ride height adjustment is explained here for the factory specs, A-bodies fall under the "V&L" lines

Just because the shocks are named "deluxe HD" doesn't mean a thing. Could be that they're just KYB knock offs, in which case they could be a big part of why your car rides like a truck.
