driveline questions (Dana 44 67-76?, eaton ho52)

[Blue_71]

my k20 has the original dana 44 "big hub" front with 4:10s. im getting ready to put it on the road as a daily driver while i put the 89 on a new non-cracked frame.

question 1-
id like to lock the front and rear... can a front locker be run daily on the street without problems?

2-
wheres the best place to get drag link ends and tie rod ends? are they the same as any dana 44 or do i have to search for specific 1971 3/4 ton 4x4 pieces?

3-
are there seals made for the axles where they bolt to the drum? im getting tired of black stripes on my whitespokes!!

thanks in advance!
