Why T181 flanges

[anticpunk]

ok, so what about changing flanges and stub axles in a type 3 squareback? Bigger CV's probably serve me no purpose anyway, but with a turbo toyota conversion in the future plans, what components would I require to do the swap? will the later 944 alum. arms fit my type 3 irs suspension? are the axle length and cv size requirements the same for me as for the type 1 guys?

Thanks,

Jay
