Hey Longfellow, if your clutch takes a dump I'll give you the Spec stage1 that came in my S14. Should only have 1k miles on it so far and feels great.
For the yoke bolts, I jam a long screwdriver through the open part of the u-joint so that when I twist the driveshaft, it hits the chassis. Then I get a long 14mm wrench and just lean on it. My weapon of choice is a Craftsman 12/14mm double box-end, which is nearly a foot long. You'll never get there with a pussy 7" regular combo wrench.
