necessary parts:
2way preferably with T18 drums (atleast the handbrake will work then)
P/S arms
Good front tyres
8/6 springs with good shocks
Make sure the radiators up to the task
oh and a bucket seat is a must
Thats the basics.
If your going to open up the engine you may aswell give the head a recon. Why the TRD head gasket? I run a modded head and block with a stock gasket, atleast it'l be the first thing to go if it over heats.
