Hmmmm from what i have in my old tc3 there's a ring gear, spool, steel outdrives. Just screw the ring gear on the spool. Put the steel cups into the spool(don't forget to grease then up) then put the proper bearings for oneways on each side and put into car. Slide the dogbones/cv shafts on each side then button everything up.
Look for the intruction manual dude. Look for anyone for any car. They all work the same.
