I have an R28 from a Carlton/Senator for sale

If you were going to scrap it anyways...

Part of a full minibus full of parts I collected for ABS

That's alright then.

So the first R28 gearbox we've pulled apart has buggered synchro's on Reverse and 5th.  Bearings are ok, but if we need to replace, they're not currently listed anywhere.... Might be able to find alternatives. Oil seals would be required as well....

I was trying to avoid changing gearboxes as a lot of effort was put into the Red top flywheel, clutch and concentric slave set up to get it working correctly.

But at the mo the gearbox in the car is properly dreadful and i've got two broken ones. It might be a case of trying to build One from the Three.

If you need to replace the bearings at any point. Try these guys, they've always been extremely helpful, even with really obscure stuff like phosphor bronze bushings for a 1980's cement mixer

Brilliant, and thank you

So I have been previously told the GM R25-R28 gearbox is a Getrag 240 box and so is the Ford MT75 but in a different casing. The casings certainly look similar, but two gearboxes companies have today told me they don't think they are the same ?

Does anyone on here have a definitive answer please ?

And a couple of questions.
Do other Omega gear boxes fit the V6. ie is the bellhousing bolt stud pattern similar on any others.
Are any of the synchros on say other omega gearboxes match the R25-28. My gearbox man thinks he can build a box up from bits. Just syncros are the issue. I need synchros on reverse and 5th. I potentially have a spare but not sure. Just wanted to ty to maybe get another or suitable spares.

Basically the petrol derivatives appear to have a consistent bellhousing bolt pattern 1.8, 2.0, 2.2, 2.5, 2.6, 3.0 and 3.2
