steering box rebuild.

[Hitchhiker]

While have my engine out for replacement, I took my steering box out on the pickup, as it has a lot of play and I have heard they are hard to get out with the engine in pickups. I've searched thru the archives and looks like everyone recommends getting the service bulletins to rebuild it, I plan on it, but I would also just like to order the parts I will need with it. Does anyone offer a good quality full kit? So that way I can just do it and make it perfect? How are the Snyders or Brattons rebuilds? I was thinking about just getting one of those.
Is there anyone else you recommend? I'd rather do it myself, but also if it's going to be close in cost after you figure machine shop cost to hone and maybe press on the worm gear. I might be better off with someone elses. I'm also trying to get this thing done ASAP as it is my daily so ordering the service bulletins,waiting for them to show, then ordering what I need sounds horrible as the engine is almost ready to go.

thanks for any advice
Matt
