Hello All
I'm attempting to put a 5 speed 4x4 and t-case trans out of a 92 250 in a 91.5 350 with the 8 in frame.Both trucks are Cummins diesels. The 91.5 had a 3 speed auto and was 2 wheel drive. The 91.5 350 will become 4 wheel drive but not right now. I'm just trying to do the trans swap first. I've got the auto out and I'm pulling the 5 speed now. I've hit two bumps in my plan. I've figure out that the tunnels are not the same. My 350 is narrower than the doner 4x4 250. Since I'm not going to complete the front end swap right away it looks to me that if I skip installing the lever for the t case shifting the new trans ought to go into the narrower tunnel.
Am I Right????
The other problem is the trans mount cross member is way different between the 2 trucks. Is it different because of the auto to 5 speed or is it 91.5 to 92 design change or is it because of the t-case. It looks like none of the holes in the frame are going to line up with the new cross member. And the really bad design with the trapped bolts on the top frame rail that are held in by the cab.
Help!
I'm contemplating pulling the cab to get the new holes drilled. Is there an easier way?
Also I know where there is a 2 wheel drive 5 speed for sale. Will it work with my old cross member from the 727 auto trans? I have to drive this truck to Florida from Michigan this coming Friday. I'm pulling a 8000 lb trailer which is why I decided to go with a manual trans. If It can be a bolt in I'll use it for my trip and pull it when I do the front end swap.
Look forward to some advise
