The gearbox on my '94 9000 Aero has a non-repairable cracked casing so I need a new one. The question is do I have to use one specifically from an Aero or are there other models it can come from (e.g. a 2.3 FPT) and if so, what years can it come from (or even better, part numbers !)

Thanks

No idea why it cracked (possibly God getting revenge for several years of sinful living), proving quite hard to find a replacement (except for a new one from saab, which would cost about a bazillion quid....), but still, I am determined that this will not be the death of the car.

Also, taking from the other post which was about gearboxes:

"Version 4:
GM75701
'93 CST, CSET and Aero
3.61:1 final drive with *needle bearings* behind spider gears
Front dipstick for level checking and filling.
Large inner driver.

Version 5:
FM751xx
'94 CST, CSET and Aero
3.61:1 final drive with *needle bearings* behind spider gears
Reverse-gear synchro, and revised synchro and selector function throughout.
Fill plug, level plug, drain plug, no dipstick.
Large inner driver.

Version 6:
FM751xx
'95-'98 CSET and Aero
3.61:1 final drive with bushings behind spider gears
Reverse-gear synchro, and revised synchro and selector function throughout.
Fill plug, level plug, drain plug, no dipstick.
Large inner driver. "

According to this I would need the 'Version 5' 'box but can anyone tell me if I can get away with using either 'version 4' or 'version 6' on my car or will they not fit (just so I can widen the search for what parts will do) ?

Car is a '94 9000 Aero.

Thanks

Perhaps there is also Version 7, it is similar with Version 6, but final drive ratio is 4,05.
No idea about inner driver.

I have '97 9000 cse 2,0lpt, and i=4,05 is on type plate on gearbox
