Thats a great idea, they are who I bought my kit from, I wanted and tried to use a manual box, it bolted right up but finding a pitman arm to work drove me up a wall! welding one up crossed my mind for about 2 seconds! So I switched to a power box, kinda glad I did anyways. I liked the way the truck handled with the stock box and straight axle, at least I was use to it that way
(If headers could have fit I would have kept the stock steering) Once I get the lowered axle, king pins, new style tie rod ends, 1" tie rod and shocks, I'll bet I will be saving very little bit of $ once you add the disc brake kit and PS, as compared to a base kit IFS, Still I just like straight axles for some reason.
