these are 15X7 D's on my 68. The front tires are 215/65 and the rear are 245/60. I trimmed the rear wheel lip slightly on both sides and raised the rear slightly with shackles (trimmed). The front end sits a little higher in last couple pics (on purpose because of deep oil pan) so obviously there was no rubbing then. If I remember correctly I removed the top bolt on both sides of the front wheel well before I raised front end. The tire rubbed that bolt so I eliminated the source of the problem.
Drove it hard through Deals Gap without issue.
