904 Slip Yoke, Drag Race Damage, Please help !

[pilotsf]

So back again guys,
I have a 70's to 80's 360 and 904 In my 68 dart original slant 6 drive shaft, and the bushing and slip yoke are shot from drag racing. Im all ready for repair but don't know about the slip yoke spline. (7260) small u joint. I have seen 25,26,29,30??? I thought 25 was 904 and 29 was 727. Also Anyone know where to buy a good one.
THANK YOU
DALE

Call my friend tell him Marty, supershafts sent you, 515-282-9996, ask him if he is still making the 1310 version and then you'll need either a 5-353 or 5-788 spicer joint, then when you finally get rid of that factory shaft you can go right to 1310 and lose that old dead detroit series

Pull the driveshaft and count the splines.
I have a bunch of stock 904 yokes if you are looking to repair what you have.
