I believe my car left the factory as an MOD model but by the time of my purchase 10+ years ago a BW Autobox had been installed by the PPO. I then sourced a rebuilt 4 speed OD box which I believe to be of the correct type for this car and fitted it as part of a complete mechanical overhaul. The auto propshaft and gbox mount no longer fit this setup so I sourced a horseshoe type mount which again, I believe to be correct for this year model and seems to fit OK. Although I am not sure if I have the correct spring fitted? For the propshaft, I found 2 sections in the spares pile that combined to fit the car. There is a 34.75" long rear section with U-J's at both ends and a slip yoke with gaiter. The front section is 17.5" long with a UJ on the gbox end and incorporates a center mount with bearing and rubber isolators which looks like it may have been a factory piece but was then modified/strengthened with a piece of welded rod. I have mounted it temporarily using a couple of alu spacers to what seems a reasonable height/alignment. It drives OK but I am getting a slight vibration pulling away which may well be those perished bushings I am guessing.
Does anyone recognize this center mount or know which model it may be from? All the Jag manuals & parts books I have only show varying length single propshaft setups for the S Type, length dependent on having auto, manual or MOD boxes fitted. Its obviously in dire need of some new bushings and ideally a new center bearing but no idea what it is from to order those parts? Also do those 2 lengths (34.75+17.5 = 52.25) add up to what a standard S Type MOD propshaft should measure? Does anyone else have 2 piece prop setup like this or do I have the wrong gearbox maybe??
Any help in resolving what is the final hurdle to getting this one back on the road for the first time since 1984 I think is greatly appreciated.
