the one in ur v6 is a t5.. i don't believe they have ever made a t35... and a t45 is a 4.6 gt tranny
the v6 and v8(5.0 not 4.6) tranny crossmembers should be the same, because the trannys are identical except the gt internals are stronger and have different 3rd and 5th gear ratios
and i'm pretty sure the driveshafts are the same as well..
they have the same ford racing part number for an aluminum driveshaft
