72 Blazer U joints / cross question

[D.PASSMORE]

I have to rebuild my D44 front axle, leaking seal on PASS side/axle tube. I have a few questions:

1) Who sells a sturdy, complete kit - seals and bearings for a 72 D44?

2) Any good advice before starting.

3) Does any one have any part numbers for the U-Joints/crosses in the axles and the part numbers for drivshaft u joints / Front and rear?

Trying to avoid stopping and starting due to incorrect parts or knowledge base. Any help would be appreciated.

Thanks
