I just finished a 300Tdi conversion and I have the following parts left over:
*300Tdi transmission tunnel
*300Tdi Floor pans-both sides
*stock 300Tdi radiator
*stock 300Tdi Intercooler
*stock 300Tdi driveshafts
Call me at the shop if any of this will help you.
P.S. I also have a pair of 300tdi trans mounts (rubber) but the threaded ends are chewed up...new ones are cheap but you can have these for the cost of shipping if you're so inclined.
