After an exhaustive 3 week, steel wheel, Googley search, I've come up with an almost perfect match for wheels for the 507. Rudge wheels were on the BMW as well as Porsches of the day. They are unique in that they are pin drive (read, knock-offs) and have a very unique center section. Size was 16x6. Yep... that's a big, skinny wheel!!
Now, with real Rudge wheels climbing up past the $16k mark, and keeping with the design philos...philasof...fila..
..idea here of using extremely similar, easily found, parts to get the look in after, these 2015 Ford Transit wheels are a pretty good match! Way better than my last selections. The center section has the bulbous look of the originals and they are 10 hole as well. Although these are 16x6.5, I will send them to a shop and have them narrowed along with a standard 5x4.5" bolt pattern installed. A thin chrome trim ring on the outside and a simulated knock-off of my own design, or the dog dish caps I have, will complete the look!
Interestingly, I've had several people ask if I could build them one when done... how cool is that?! Way cool, I know!!! But I don't think that's going to happen for a number of reasons. Still neat that there is interest!
Cheers
