Thanks for the help!
One of the MR2 forum members in Australia organises shipments time to time straight from japan and he had a few wheel sets which included the TE37's.
Unfortunately the wheels got sold before i could arrange to buy them
I'll probably will head down the the local wheel stores now to see whats available in 40 offsets now (Cheers for the advice)
I'm assuming smaller width sizes would have no issues too? 17x7 & 17x8
