I picked up a used Tamiya TL01 mostly complete chassis, with only the body and servo missing, but the driveline seems a tad sloppy, so, i am wondering if parts from any other models (gears, diff's) are compatible with that chassis, since, although i can find the gear set, i can't seem to find the diff's for it. My plan is to take it apart, clean everything, see if anything is wore out, and replace all the bearings, as well as the servo, and while i am at it, replace any broken or worn out parts if they are available. I would also like to make it brushless, so any upgradeable parts info would also be greatly appreciated.
