Zero rate & front driveshaft?

[WhiteBurb]

I'm going to make a set of "zero rates" out of some old overload leafs I have. How long should they be? I was thinking long enough that the ends are just past the u-bolts.
Also, is there supposed to be some sort of a seal on the front driveshaft slip joint? Whenever I lube it, all the grease comes out of the joint.

Thanks again

just past the u bolts is good, just make sure to but a center pin through the whole pack

and there is a seal that goes on the slip yoke, you should be able to unscrew a thin stamped cap from the female side of the slip joint to see it
