dqami Posted September 12, 2008 Report Share Posted September 12, 2008 I'm looking for a 78-79 driveshaft or even just the input part so I can put in my 5 speed dogleg into my 521. Anyone have one or know where to get one? Link to comment
datzenmike Posted September 13, 2008 Report Share Posted September 13, 2008 I think all you need is this: http://i138.photobucket.com/albums/q251/datzenmike/620stuff003Large-1.jpg[/img]"] The 521 has a flange output F4W63 tranny so the drive shaft will have the flange like the top one in the picture. (just ignore everything to the left of the two flanges that are bolted together) All you should need to do, is take the top and bottom drive shafts apart at the U joint and take the spline from the bottom one, and swap onto the top one.

dqami Posted September 13, 2008 Author Report Share Posted September 13, 2008 Hey Datsunmike, yes I need the bottom input shaft from the ujoints off the 200sx. My 71 has a 2 piece shaft and I got a 1 piece shaft off a 69. I assume the input shafts are the same since both are 4 speeds. I'm wanting to go w/ the 1 piece shaft for the 5 speed. Link to comment
datzenmike Posted September 13, 2008 Report Share Posted September 13, 2008 Tranny splines are the same it would be the length that matters. Can you measure the length from the center of the U joint? Here's a couple more, some have a longer spline. I keep them to plug spare trannys so the oil doesn't leak out. http://i138.photobucket.com/albums/q251/datzenmike/00270010.jpg[/img]"] Link to comment
dqami Posted September 16, 2008 Author Report Share Posted September 16, 2008 Right now I have it parked elsewheres so I can't measure the 2 piece on the truck. here's a pic of the 1 piece. I tried putting it into the 5 speed but it doesn't quite go into it just right. So you're saying if my 4 speed has the short input shaft, I should be able to swap it on the 1 piece, or just use the 2 piece shaft and it should fit the dogleg? Link to comment
datzenmike Posted September 22, 2008 Report Share Posted September 22, 2008 Ahh. No, not saying anything, actually the pictures are of 620 drive shafts and the primary drive shaft off a 720 4X4, but it does work as a good illistration. The long spline may just be going in and bottoming out. A shorter one swapped on might work fine. In a pinch you could trim some of the long spline off as you can see down into it about an inch to where the splines start. This would allow it to slide in further. Try a shorter one first. Test fit by hand then change it at the U joint. Link to comment
dqami Posted September 22, 2008 Author Report Share Posted September 22, 2008 Thanks. I'll do that. Link to comment
datzenmike Posted September 22, 2008 Report Share Posted September 22, 2008 dqani, If you can, take some pictures showing how you did this and the parts used.. Link to comment
