    How do I know how much to have my rear driveshaft extended? The splines are showing about an Inch outside of the yoke and it keeps falling out when do certain things driving. It's 22inches from weld to weld and I figure on adding about an 1.5" to the tube is this enough?

    You can't just "add" to the length of a driveshaft. The correct way to do it is to cut off the ends and weld them to a new, longer tube. The drivesahft shop will tell you what points to measure from, then will size the tube accordingly.
