Hey guys, while chasing some old Jeep parts and checking on an ebay 5 speed from a `48 that we didn't grab, I had an epiphany about a long convoluted way to get a poor man's OD for running behind the original 230 in my old man's Pilothouse 1 Ton. So bear with me: He wants to keep the stick and the original rear end, he doesn't want to cut the floor more than necessary, and really wants to keep his "deep first" granny gear for crawling up out of his long, steep driveway (I'm not exaggerating either - couple hundred feet and varies between about 10% and 40% in grade). So the truck has a T9 in it that he's fine with other than the 1 Ton having too short a pumpkin but he doesn't want to change the rear. So, after much research, I hit on the fact that the T8/T9 were the forerunner to the T98 and the grandaddies of the still quite common T18/T19. So what if we put in a later truck 4 speed that we can "somewhat cheaply" adapt to a Dana 18 transfer case that will accept a Warn/Saturn PTO overdrive? Options abound for Dodge New Process 435's as well as Dodge & Ford T98/T18/T19. There are lots of options for the Tcase adaptation and the extra weight is really a non issue in a 1 Ton that's already heavy and always running an empty flatbed. It sounds like a winner IF I can fit one of these later transmissions into the bell of the old 230 without going too crazy. So here are my questions: 1. Does anyone have the specs for the input shaft and bell housing back pattern on these? I know on my Fords the bell's rear is pretty much identical up until they went integral and the variables are all input shaft length, diameter, and spline count. What's up with the old 230 Dodge? I can't seem to find any specifications on this kind of stuff on the web (shaft length, spline count, pilot bearing diameter, etc.). 2. Given the above, the next question (or maybe the real question) is how hard is it to adapt the later truck trannies? 3. How big are the differences for the tranny interface specs (drilling a few mount holes isn't scary but finding a correct or adaptable input shaft is the question) between the old Dodge and my Ford trannies? For instance, I've got a 4x4 T19 sitting out in AZ that we could make a great start with... So what say? Does anyone have either the answers or the raw data so I can find my own? I know you guys have got something! Share with me for the old man's sake! ;-)
