Hi myrod, here is what I am or was trying to say above: with that excellent EIZR-6394-ZZ Bell Housing these are your options for a T5 Transmission.Hi Bubba,,,,,,,,,,,,,can't follow you,,,,,,,,,,,,,,,,,,,,,,you are saying that either T5 transmission will work equally well (from the 5.0 or the 4 cylinder). Also, having the E1ZR-6394-AA bell housing doesn't make any difference, I'll still need an adapter? As far as the Rear Axel Gear Ratio goes, I haven't gone there yet.
