the car is 125" W.B. to start the axle was 8* caster and had moved it back to 12* and up to 5*. monday I talked to a street rod guy he said they run 5-6* caster and 1/16-1/8" toe in for biasply and 0-1/8" toe out radial. so I set 5.5* caster and almost 0 toe out for my radials and took it for a test drive on the old back top seamed to handle good and no shake. do you think I should try running more caster? on my old 161" F.E.D. I ran 22* caster and 1/8 toe in with good luck.
