Ordered my driveshaft stuff from Ontario Engine & Machine:

http://www.ontarioengine.com/

They had the best price on the shaft/sleeve - $175.65 for the shaft and sleeve

At any rate, I ordered it a little over a week ago and had not recieved, so I called the number. The owner/manager Vic Logan answered. Super nice guy, he remembered the order just by me saying I ordered a long travel spline and some 1410 stuff. Was able to find it without me even telling him my name. He looked it up, its due for delivery today. I then spent 25 minutes asking him questions that he answered completly. Even gave me tips on how to machine some of the stuff to work. If any of you guys are going to make a long travel, I would use them for parts or the entire shaft.
