I've got a Tremec 3550 with a standard length 10 spline input shaft. I also have an output driveshaft yoke that that goes with it. It came out of my Lone Star behind the old 428. It was a 2001 Tranny with 6500 miles on it. It has never dripped or seeped a drop of
oil. It has always shifted great. The car has never been tracked or 1/4 mile'd. The input shaft IS NOT an FE (5/8" shorter) input shaft. I'm looking for $600, plus shipping. PM me with your zip and I'll give you the delivered price, along with answering any questions.
