stupid question.....

NO, not on hand, but your right, it is shorter by a little bit. I forget the exact length difference between the 904 & the 727.

I understand you can order it from Summitt/Jegs. They use a company that probably has the length on hand.
I gotta do one for my /6 to 318 swap. I changed the 7-1/4 to a 8-1/4 rear. The shaft doesn't fit.
