    I need to know how much drop my drop pitman arm needs to have. Its an 84 with 4 inchs of lift. Im doing the crossover/hi-steer combo on a 60. I did a search and all I found was the part numbers for the 1.5 and 2 inch drop pitman arms, but didnt find out how much drop I need. Thanks

    Basically, this is the best thing to shoot for.

    Is that the Ford Van pitman arm or aftermarket? All I'm asking for is the amount of drop that I would need? i got from the links above that you can use a van drop pitman but no one knows the year or model of the ford van to use, and even then you still have to hone them out to fit the DLE of the chevy. I know companys make aftermarket pitman arms but I dont know how much drop is enough or to much for that matter. Thanks for any help

    Well if you can get 1.5 or 2" drop arms, either would probably be fine. I never measured the drop on mine that I got off a 78 Econoline (some people do know what year). The arm can be found on the econolines from 75-79 I believe, if not more places. I've heard there's some F-150's and wagoneers that have them too. I paid $3.50 for the arm at the yard, then paid a local machinist $20 to ream it for a chevy 1-ton TRE. Not too much work really. Just stay away from the big 4" drop arms that everyone uses. If you want I can try and figure out exactly how much drop mine has, cause it came out to be just right.

    That's not completely true, it was a year thing, not strictly a 2wd/4wd thing. My 2wd box swapped right in, and I've seen 4wd boxes with both sizes.

    I'm not sure. We've had so many steering boxes around here, with four trail rigs being built out of the same garage. They're all mixed up, and when it came time to use them, no one could remember which is which or where they came from. I suppose I could have looked to see if it followed the o-ring vs. flange issue for the lines, but I never paid enough attention. We had enough of the different rag joints around so that it didn't matter. Eventually, we just got into the habit of disconnecting the steering shaft from the rag joint when we pulled boxes off a rig, so that the rag joints stayed with their respective steering boxes. Then you never have a problem.

    Well I'd be half doing it out of my own curiosity.

    word! the 2 different input sizes dont really have anything to do with 2wd/4wd. at one point in time i knew which size wrench would fit over each at the splines and flatpot:doah:
