Getrag 265: 262.0.0510.90 vs 00

[3.0CSi]

Hi.
I know this matter has been discussed many times before. But I cannot find an answer for this particular question. And it seems not much know the answer. I hope I'm wrong...

I'm looking for a Getrag 265 CR to couple with a M90 engine.
Recently I've found a guy selling two 265s on the net. One is the 262.0.0510.00 and the other the 262.0.0510.90.
I thought the latter was a CR, but through my searches, I'm not sure of anything anymore.
Does anyone knows what those 262.0.0510.?0 numbers stand for? What's the difference between them?

Thanks

My spare 265 OD trans has 262.0.0510.00 on the case if that helps.

Thanks. I always get the feeling that the 00's are OD and the 90's are CR. But I can be wrong.

The gearbox is this one. I'm almost sure it is a CR. But would like to be really sure before I buy it.

The rear case looks different than mine, where is the speedo drive? Other differences too.

Visual ID

"the center section has the same bolt pattern on either end so the gasket is the same from the front and rear sections"

On the OD trans the bolt holes are staggered rather than lined up at the front and rear of the case.

The bolt pattern was what convinced me it's a CR. Thanks a lot.

Given I have the original 4 speed gearbox in the car, how will the bigger 265/5 fit?
