Yes, but they are difficult to find, and usually way too long. The Cummins
178539WRZ is effectively slightly longer, mostly because it rides lower in
the pulleys. I had to special order it through a Cummins truck dealer.

The belt that used to be supplied (NLA) was marked 20x900. I don't know how
that was measured though, the standards have apparently changed. Jim
Wallace made a post about a year ago about current Gates belts that would be
close in size, you can find it in the archives.

Not without significant modifications. The hub is too short (needs a spacer
behind it), and the surface for the front seal is smaller (needs a special
seal). The ID of the hub opening appears to be OK, but I haven't actually
tried it yet. Someone mentioned a harmonic balancer from a 5.0 Mustang, I
plan to look at that next.

Yes, BFE, Revington, probably others carry them. _Might_ be able to use an
original TR6 pulley, with some mods. BFE carries the entire kit to convert
to a narrow belt, but it's not cheap.
