Door handles: the 507s were a very slim line design and while looking at them, thought they looked eerily familiar to me. Then it hit me! 1955 Chrysler 300C!
Once rechromed these are just about identical to the 507 in operation. No lock in the handle, but that's ok. There's ways around that! Man.... can't wait to start on this thing!
Tires are 6.0 x 16 which are pretty close to the old Chevy truck tires. The times are becoming a fun search. The last set of German Rudge wheels, restored, were sold for $16k a set. Along with that, you need the adapters for the axles. Well, homey don't be having no $16k for wheels laying around, so that's out. What I've found that's pretty close are spare tire rims from Fords and Chryslers. The rims are 16x4.5 usually. Will post up more as I zero in on a final selection.
Cheers
