I lost a large photo file awhile back so I'm missing my conversion photos. Here is the DSS convertion page. The slip joint is located at the rear of the shaft. They explained that's where the most movement is in the drive line so placement at the rear reduces the stress on tailshafts. Many driveshafts will show the slip joint forward, but this idea has been changed. Myself as well as others here have had cracked tailshafts over time.
Ricky Hall has this conversion on his wagon and he has posted photos

Another option is just change the driveshaft. Driveshaft Specialists do Ball & Trunion conversions for A833 & A727 all the time. They did one for me and several for friends check it out. My conversion is a standard 4" shaft, Spicer Flange/U-joint, Slip Yoke rear with U-joints to remove vibration and movement from tailshafts, rated @ 600 hp.

I would like to change the flange to a slip yoke on my 64 4 speed 833. What do I have to change and do I have to change the output shaft and gears. The reason I ask is the housing.That I have is for an 3 speed overdrive trans. Any suggestions would be greatly appreciated.Thanks Jeff
