Thanks for the suggestions ! I have the kits mentioned so I did some checking . . . the Monogram '59 Caddy tires aren't even close . The AMT '57 Chrysler look identical except the tire lettering isn't as crisp , maybe they were also in a newer kit ? I don't think they are Modelhaus as I got them on Ebay really cheap . All four whitewall inserts are identical so I'm thinking they all came in the same kit , guess that's not necessarily true . The fronts I can't find anywhere .
As for the Cragars . . . The El Camino and Chevelle Wagon have really nice ones but they have a deeper offset than these , not concerned about the mounting posts . I also checked several other AMT kits that have Cragars and either they don't have the S/S caps or they have different offsets . A couple like the Baldwin Motion Camaro has a really nice set but the spokes are more rounded without the flat tops , I've seen real Cragars both ways so it seems both are correct .
I'm not to concerned about finding the Cragars but I really want another set of the tires so I'll keep looking . Thanks guys !
