Where can I buy a rebuild kit for a non world class t5? Can I use a world class rebuild kit with new bearings thus turning the NWC into a WC? The reason I ask is because I got a NWC for free. My current t5 wont go into second gear wheather i chewed up a blocking ring or wiped out the gear entirely. So I was gonna use this other tranny to get me by for a bit untill I can rebuild the good t5 and get a clutch and so on and so forth. The reason I have to rebuild the NWC is due to a bad third gear crunch from a synchro. I have yet to positively determine if the spare is indeed a NWC but judging by the bearing cap to the lower right of the bearing retainer its the NWC because it is not stamped timken.
