100% with ya there! Their site is SLOW and not informative!!! If I want information I come HERE (or I talk to TonyP if I can find him - he actually gives information. . .)
Personally, I haven't had any problems with my gears, except for the spurs (picked up some crap and chewed them up), but my buddy spun his rear diff and melted it right out. We THOUGHT we had it set right . . . guess not.
Well, find out if we can get some delrin gears done. . .I would be happy to hear it!
