I was on the ph with Mike at Rossler and there is no real way to save my drive shaft with a shorter th400 even with a 9" tail output it comes more than an inch short.I can get a longer th400 yoke 6" I believe but is not enough.The th400 is 33"7/8"long bell to tail.and the 727 35"1/4" ps:I indexed my trans on the firewall and marked center so I can test fit the new trans asap.The engine has 2" to the firewall from the back of the engine.
