T5 trans swap question

[dhamilton62]

So for anyone that's done the T5 swap in their C10, did you guys fab up a rear support for the tail housing on the trans? I heard from some that if you have two mounting points on the bell housing already than a rear support isn't needed. I ran it without for a test drive and all the gears felt great until I went on the freeway in 5th and on de-acceleration, and coasting in 5th there was excessive vibration and noise until I put a load back on the truck. Could that be a caused from not having the tail supported from a frame brace? Thanks everyone.
