Gary,

Maximus Hobbies in York, ME just got a big shipment of parts in.
Heath, the gentleman who runs the shop is great to work with. His
number (at the shop) is (207) 351-1520. That's the only place I
know to go for these parts.

The size of the diff/thrust balls is listed (I believe, not at home at
the moment) in the manual in the section on building the diffs. I'll
have to check if they are metric, and if they cross-ref to a convenient
SAE size.

I honestly think the thrust washers on these things are made from
grade-A hardend butter. The one in my rear diff was distorted as
well, but the whole diff still works fine. When I found mine was
deformed, I put it back together the way it came out, with the upward-
bent part of the washer facing into the thrust balls again, so it
serves to capture the balls. I can't promise that this will fix yours,
but hey, anything's better than buying lots of parts.

There have definitely been a few different revs of this car built.
Mine was an earlier rev with chrome rear lower-arm pivot pins.
The two newer ones I saw at the track last week both had black-
colored hinge pins. All the screws on mine were over tightened,
so half of them are stripped. It looks like the newer cars are
torqued to a lower spec, since the one I was working on had good
bite in all of the screws. The one with the failed diff was one of
the newer cars.

If I remember, I'll try to pick up a TC3 or PRO-4 diff kit at the
shop this Friday when we race and see if I can reuse the ring
gear with all new hardware. I'll let you know how it goes.

Mike
