I had the exact same problem with my 67 4x4 1/2 ton. My manual box went out and was sidelined for awhile. Everyone I spoke to said the only thing that will work short of fabricating was another 67 or earlier manual 4x4 box since the 2wd were different. I finally found another manual box at a junkyard. Good luck with the search, I know it's a hard one.
