I really suggust using the 15"
I have a Lacarra Mark 4 GT 14" O.D. and it sort of gets in the way of the gauges. Just enough to be irritating.
I like the Grant too. They both don't have the dish of a factory wheel, so the wheel moves forward. The adapter is about 2 1/2" from the column. But the rim is still forward of a factory rim. You might want to make/add a spacer. If you don't want/need the spacers you should bend your turn signal lever forward. I used to always bump mine. Personally I'd like to add something like a 1" spacer.
Tuff wheel repro would be another option. I think they are a little bigger diameter to see guages.
