[Aubrey N Bruneau]

Naah, Jack... nothing to move back there.
I ended up removing the whee;s/tires, and edentifying exactly where the contact was being made on the inner side of the outer wheel well panel ( these cars of course have a full "tub".
Wasn't much, but both sides, definitely a problem, same area, about 4" long.
It was a little crude, but I simply "squeezed" the inner panel at that spot, a little closer to the outside ( MAYBE 1/4" ).
Seems fine now.
I'll put a shade of chalk on the sidewall of the tire ( at the maximum section width ), and drive the car a bit to make sure.

Radials ?
I dunno man
With this thing, the temperature, track, and all the cloud-to-sun ratio has to be perfect, or it spins the tires off !
