4 speed od or 5 speed

Since we're off track and on this discussion, I agree with furyus on the T5.

After many installations and experiencing several TKOs, I can say its the biggest piece of #*$% on the market. I'd do one of 3 things, 4 speed and highway gears (my poor mans OD), t5 for non abusive situations and a T56 as the ultimate, knowing the degree of fab necessary.
