12 bolt rear questions???

[bigfsh]

Well I just recently acquired a 12 bolt rear out of 79 lwb. When I picked it up I noticed my buddy had cut the e-brake cables. How hard are those to change out?  how hard would a disc brake conversion be?

Cut the ends off?  They are a pain but they can be removed with some tension and a screwdriver.

Rear discs are more of an undertaking.
