need to drive line tailstocks for a huber or borgwarner trans..

I'm confused. When you refer to a "tailstock" for a driveline transmission what comes to mind is the rear addition to the transmission body that is used for a "plug-in" application that the drive's input shaft plugs directly into. I have never seen, nor heard of, a plug in for a driveline application. I have tailstocks for plug-in applications for #3-5 drives as well as a pair of tailstocks for plug-in #6 drives.
