Rebody Oh no. It's not another 507 Rebody. Oh yes it is!

A pair similar to this one with the correct size and bolt pattern could combine mesh and center knocks.

Maybe a more 'full' look would be good for this type of body. I don't know what your tastes are, but something like this? View attachment 325577

Yes. I do like the pepper pots. But they're only available as 15"

I haven't given up on something similar though

Still trying to decide what wheels.

What do you reckon to BBS Mesh style (BMW Style 5 ish) with faux knock-on spinners (This is a mock up)

I don't think I ever saw a real 507 with spokey style wheels.

You need to decide what look you want to end up with then find some wheels that will give you that look.
The above wheels scream 1980s and the fake spinners make anything look cheap and comedic IMHO.
Style 34s or 36s are as near as you will reasonably get to the originals from a 507, if that is what you are after.

The wire wheels with real spinners and hub adapters are 15". 65 profile tyres and a set of lowering springs and job's a good 'un.
