Any one out there know if they make an adapter to go from a 4 lug blot pattern to a 5 lug bolt pattern? Its hard to find a nice wheel in a 4x100mm pattern with a rear wheel drive offset to fit the Chevette. I have 4 aluminum rims off a Ford Escort but the bolt pattern is too big. I would file the bolt holes to fit, but I don't know how safe that is ,and I'd have to get spacers for them.

Since you already have the Escort wheels, a simple solution would be to have the Chevette axle flanges re-drilled to the Ford bolt circle, between the old studs. Press out the old studs and press in new ones (long studs if you want to run a spacer). You'll want to check the lug nut style too, since the nut seats might be different on the aluminum wheels that the old steel wheel lug nuts. Filing the holes would be a very bad idea.

Any good machine shop can redrill the wheels if the back is designed in such a way to accept the new holes.I had a Pinto station wagon in 1979 and could not find any wide 4 lug mags at that time. I got some 5 lug slots and welded the holes up then had a machine shop redrill them for the Pinto pattern.It worked great and I was the only one with 14X8 rear wheels on a stock Pinto.
