According to guru Dave Patten as noted here on the Realm, these should fit:
The VTO wheels FutoFab sells include a +18 offset 15x7 wheel (Retro 4 & Lemans styles). These w/205 tires fit well on a stock strut 510 with rolled fenders.
Would prefer excellent to new condition rating, but will entertain used wheels. Color not important unless you painted them purple or something.
I have some Panasports in 13" I would consider trading if someone is interested, but not an absolutely necessary part of the deal.
Please PM me with info. Thanks.
