      '66 El Camino:

      F-18x8.5 w/ 5.2 BS, 255/40-18
      R-19x10 w/ 5.5 BS, 295/35-19

      Baer GT front brakes and Baer Touring rear brakes. The rear fender lip was trimmed and rolled to ensure more than enough clearance.

      '66 Chevelle SS:

      F-18x8 w/ 4.75 BS, 255/35-18 (will eventually change it to 245/40-18)
      R-18x10 w/ 5.5 BS, 295/45-18

      Same brakes and fender lip trimming as the El.

      Pictures of both are in my PT Garage.

      Here's mine: 1967 El Camino, lowered quite a bit.

      front: 17x8, 4.75 BS 245/45/17
      rear: 17x9.5, 5.5 BS 275/40/17

      Stock 10-bolt w/Camaro LS1 rear discs
      Front SC&C stage 2 kit w/Kore3 C5 front discs

      Fits with no cutting or rubbing (so far) even with front inner fenders in. I do have 2.5 degrees of camber which helps the tire stay away from the inner fender bolts.

      The front is the same, not sure on the back. Just looking at Bob's 66 specs, the wheel well may be smaller on the chevelle by a little, since I didn't have to cut/roll the fender lip at all.

      67 Chevelle: 19x8 4.75" backspace and 245/35/19. Rears are 20x10's with a 5.75" backspace, and 285/30/20's. Close to the outer fender on the rear, but they clear.

      I actually have a set like these I need to sell:

      Here's a 20x10 rear with a 285. There is roughly .375" to the outer fender (the inner lip) and about .75" on the inside. The way my exhaust is run though, it comes close... like .375" close. But it clears, and I'm cutting off the exhaust tips anyway.

      I haven't actually measured it, but eyeballing, I'd say both of my cars have at least 1/2" clearance on fender side of the tire and close to 1" on the frame side.

      If you're not in a hurry for the info, I can measure them on Monday.

      any new pics of the Buick? What aspect ratio of 295 are you running. I hope to have my wheel tire combo ironed out and ordered very soon.

      Thanks for the pics. I think I want a little taller. I am leaning toward a 285-40-18 I got a junk 295-35 here and try to find a 285-40 to do some eyeball comparisons on
