Having suffered a driveshaft failure coming back from Stoneleigh, I have now repaired the hole in the gearbox and fitted a new driveshaft. My issue is that the tri-bearing on the inner joint is very close to coming out. I can feel the bearing edge through the rubber boot. It will drive I'm sure but it's like the driveshaft is approx. 1.5" too short. I bought the standard nearside driveshaft that would have come from the donor car (1.6k Rover 400 Tourer). I've altered the suspension settings to try and get the angle down so that as it becomes straighter, the more it engages with the inner joint. I'm even thinking of making a new gearbox mount to pull the engine to a greater angle in order to straighten the driveshaft further. Seems a lot of work for a part that should just do its job...
