37 Chev with Mustang II Alignment Question
I recently bought a 37 Chev 4 dr sedan with Mustang II front suspension and 4 bar coil over narrowed Ford 9" in the rear. Previous Owner said it had just been aligned, but Camber looked positive on one side and negative on the other side. Took it to a good alignment shop and it was way off all around. They were able to set up front end and rear all except getting positive Caster on the front. Currently at -3.2 on left and -3.5 degrees on right. The upper A arms are hitting frame on rear of arm preventing getting positive Caster. In driving it it seems to drive OK. I read one post about rake also affecting caster settings. With 29x18.5.15's on the rear it has a bit of a rake. I know it is possible to add adjustable upper arms, but what are problems for this amount of negative Caster? Your kind opinions would be appreciated!
