So I followed this topic's advice and bought a set of used Vectra C shafts for 55 quid to replace the horrendously worn one in my girlfriend's Croma (right side).

Installation was definitely not a breeze as I thought going by some descriptions here, but then again, nothing is truly easy on this car. Big issue was I bent several T-handle sockets wrenches before I borrowed one beefy enough to undo the axle nut. The oil leaking out of the gearbox with the shaft removed was also unpleasant, it's much more than I'd expected it to be (should've been better prepared).

However, the main problem: the top bolt for the Vectra C triangular mounting bracket would not go into the hole on the case. The two bottom ones were no problem, but no amount of sliding or prying would get it in, I spent an hour on this at least. It would go into the case just fine without the axle bracket (so the hole or bolt are not at fault), but once the bracket is there, the holes never seem to align, and of course it's such a tight fit I can not really see or check why or how it's off.

It's on with only two bolts now as she needs the car asap, but I'd like to sort it properly at one point. Any thoughts?

Hi, I did this modification a while ago and had no issues with fitting the new center bearing support. Getting the old one off was another issue. I assume you are fitting it to the second set of mounting points? The only thing I can think of is that there is a burr or other damage to the Vauxhall mount. Even if you had to enlarge the third hole slightly it would be better than having just two installed.

Did you fully drain and re-fill the gearbox? There is no oter way to get the correct level of oil in the 'box.
