Well I am having a terrible time finding the right speedometer gear for my BorgWarner 1345. I have a 1356 transfer case, speedo gears for those are plentiful, and parts for those are much more common. What are the differences in drop angle, and case length? Can I take the 1345 off my truck and put the 1356 on my truck? The 1345 is on my 1986 F250 Diesel, and the 1356 is from a 1989 F150 300 I6. Is it strong enough to handle the torque from my weakling IDI?
