Welcome aboard Ulf. Is this something like the look you're after?
You're going to tax my memory here, but if I remember right the fronts were 195/60-15, the rears 235/70-15. The front axle was a 46" tube with a mono leaf, the rear was a touch wide so that's why those wheels don't have much positive offset. The rear offset is critical for getting that "full" look. The fronts I try to center in the fender as you look at it from the front. Some like to have it off center to the outside, but when you get 'em low enough I feel the clearance is important.

BTW, I'm curious too why you didn't go with the Reprosteel bodies from your country.
