Hi Kms40z,
i can help you with alot of parts. The digital dash i am still working on converting mainly as mine is dli version and need a rpm coverter by dakota called sgi-8. Getting the digital fuel sender will be hardest thing but i may have that sorted using old supra one i think but can get an update. To buy cluster best bet is ebay about $300.
i can also get recaro rails for driver and passenger and u can fit recaros or brides then.
the gearbox try source local as too heavy ship from japan. Pm me what your after and budgets you have i can source bits.
will update my build thread soon.
