Trying to find information on how the 1650 driveshaft is installed. I have a late build with the twin flexible couplers in the rear. No ball bearing in the rear however it does have the ball bushing in the rear metal coupler My question is on the front coupler to the engine. The flange also contains a ball bushing but is there supposed to be a ball bearing as well? And if so what is the correct order for assembly. I've looked at the schematic and I don't see a ball bearing but I've seen it mentioned in other threads but believe they are referring to the bushing.
Thanks!
