For general use, the stock front end works fine. I am in the process of going through mine right now.
I think someone said to plan on around $600 for complete rebuild. So far, my expenses are:

spring bushing set- $45
disc brake conversion - $280
king pin bushings - $40 (machine work supposed to be around $50)
Toyota Power steering box (not required) - $40+100 for pitman arm

Still need to get shocks and possibly rebuild the drag link. The disc kit is not absolutely necessary, but I decided to upgrade since I had to go through everything anyway. If you don't do discs, you will probably have around $100 into rebuilding the stock drum system.
