Well just for reference I know for a fact that my 69 springs are bad and I have more arch than you. Quite a bit actually, and my rear sags. So confirm that. I don't get any rub but I've got a little less tire than you.

My concern is that when I replace them the ride height will be all "jacked up". And I kind of like the lowered look. I really don't want to get into lowered springs etc. but we will see I guess. Not on my list right now so...
