Rick-rat,
If the 16's fill the wheel well, probably not. Possibly might lower the front by 1/2" and could add 1" lowering blocks to give a very slight forward slant, but really no more. I would only consider lowering as "finishing touch" if there is still a little too much space. Nothing radical, I'm not going to modify fenders, etc. Like I said, I am really looking for the "70's" look. If 16's are too extreme, I would go with 15's.
Thanks for replying so quickly.
