How far does LS1/T56 input shaft protrude? Yeah, I know, all the way to the pilot bearing 
I need a measurement from the face of the transmission where it meets the bellhousing to the tip of the input shaft for an LS1 T56.
I have an Unbalanced Engineering torque arm, which connects to the tunnel brace instead of the tail of the tranny. That alone should make the job easier, but the tunnel brace itself would be a major pain to remove.
There's a little more room above the UE brace than with the stock brace, so I think I can slide the tail of the tranny back above the brace enough to get the input shaft clear, then drop the front and remove it. I need to do some careful measuring, though, so I need to know exactly how far back the tranny will need to go.

I don't have a measurement from the bellhousing mount but I took one from the front plate of the tranny (where the bellhousing bolts to the tranny) and it is 6 5/8" from the tip of the input shaft back to the front plate.
