Unless you're using a California Pony Cars' classic Mustang shifter handle on your T-5, TKO, TR-3550, or T-56, you're going to need a late-model leather shifter boot to conceal your transmission's shifter. If you're running the classic-style shifter handle, you will probably run a classic-style rubber shifter boot. In any case, we like this leather shifter boot (M-7277-A) from Ford Racing. Once installed, it makes your classic or late-model Mustang's interior look crisp and ready for action. About $81, plus shipping and handling, will put this piece on your doorstep. It can be punched or drilled to match your classic Mustang's bolt hole pattern.
