I must say that I am pretty excited to slap everything together soon. I have a set of disc brakes/spindles/UCA's from @themoparman73 and the 7 1/4 rear from @AbodyBB.
I had planned on popping in a set of 1.03" T-bars, but now I'm worried they'll be too stiff with the slant.

It's the wife's car, and she doesn't seem to even comprehend the mushiness of the suspension, BUT she does notice the bump-stop hit because the car is lowered.
I'm more concerned about keeping it low without bottoming out than I am with the cornering characteristics since it's a mild-custom cruiser for a lady.

Who has put the 1.03s in a /6 A and how did you like them? I was on the Slant 6 forums and the opinions are all over the place. Most everyone here is upgrading for a V8 swap, which I am not doing, but a slant isn't much lighter than the small V8s anyway.
