In a previous post you said that I should run a drive shaft about a 1/2 inch shorter than the stock one and I can't figure out why? Also I am planning on the Mark Williams chrome moly 3" D.S. do you know the exact length I would need for a T-56 with a Strange 12-bolt? I am making 600rwhp and 600rwtq through a Mcleod dual disk, you think this shaft is up to the task for 6600rpm clutch dumps on E.T. streets?

Thanks in advance....Lys
