1/32 body screw index?

This has probably been asked before, but anyone ever come up with a size index for the body screws of the various mass produced 1/32 scale slot cars manufactures (Scalextric, Fly, Revell-Monogram, Carerra, MRRC, Ninco, NSR, Slot-it, etc.? ) Found a few bodies I had in storage that were missing the body screws.
