I acquired a 1973 IH 4x4 1010 pickup this weekend and after getting it home and getting under it I've seen two potential problems....the guy who gave it to me said ever since he's had it, it has never had a front drive shaft in it...well at first glance I see that someone has put dual exhaust on it, and the pipe is right in the way of where the frontdrive shaft would go it appears. Second off, just looking, it looks like the driveshaft would be awful close the the transmission pan...is this normal? How close should it be? Oh, by the way, its a 345 v8 with a 727transmission and he told me it was a Dana 20 transfer case and from what I see thats true and Dana 44s....is it possible someone switched out transfer cases and there is no way I can put a front drive shaft in it or something? Where can I find a drive shaft for the front of this thing?
