The D200 have a one-piece or two-piece driveshaft? When I put an auto in place of the 3-speed in my '74 D100 Club Cab with 2-piece drive shaft I had the front section shortened and fitted with a slip yoke as the 3-speed was short and had a fixed yoke. |

it is a one piece drive shaft...its standard cab with long bed..i havent poped the drive shaft off the 3speed yet but i know for a fact it is longer and am sure the splines would not be the same....my main problem is the truck has to be moveable thats why i am looking for a complete shaft and not taking it to a shop and getting one made. |

Which is longer, the 3-speed or the 904? What's the length difference? Chances are poor you'll be able to find a driveshaft you can bolt in unless you find one from a later pickup that had a 904 originally. The donor would need to have the same wheelbase and rear end to have the right length shaft. Your truck would have had a 727 if had been an automatic originally and used a shorter driveshaft with a larger yoke than the 904. |

yeah i figured it was gonna be tuff..the diffrence between the trannys are the 904 is 3 inches shorter...i found a drive line guy a few miles from me i might give a call monday hopefully they might just have to swap out the yoke on the shaft for the 904... i hope |

3" shorter will never make it. I had a driveshaft less than 2" too short wobble badly at the yoke. |

jeff, I pulled my 3 speed and popped in an 833OD. Then took the 833 out and put in a 727. You are right to suppose the spline count on the 3 speed is different from the the other trannys. Do you have a 489 case in the rear end? Different pinons will give you a different length too. Here is how to measure driveshatft length: You need the vehicle on the ground and level. Put your yoke on the output shaft. Push it all the way on. Then pull it out 3/4 inch. Turn the trans output so that the u joints will be at right angles to each other (N S, E W) between front and rear yokes. Measure from center of curve, front and back, where U jont goes. That's your length. I have several D series driveshafts made up for large U joints. Leme know if you want one. rock '64d100 |

Quote: jeff,
Sorry, Rock. Beg to differ. There is a difference in driveshaft length between the 7 1/4, 8 1/4, and 8 3/4. But there is no difference in length, between the 741, 742, or 489 case 8 3/4 rears.
Do you have a 489 case in the rear end? Different pinons will give you a different length too. rock '64d100 |

Chaarlie, I said it pretty poor, didn't I! Glad you said it right...what you say is right! IT is why I started out with a 489 question but then left out the middle part! THanks, rock '64d100 |
