I changed out the SM465 for a TH350. Found a donor truck and was able to get the column, pedals, flexplate and crossmember. It was easy to unbolt the old and bolt in the new that I questioned why I waited so long. Hardest part was routing the transmission cooler lines, but even that was easy. Had to get driveshaft yoke changed, but again it was easy. Had to wire in a neutral safety switch and backup lights, but there is enough info on this forum and google that even that was easy. All in, probably spend less about $500. Took me longer, but that was because I painted and rebuilt what I could.
