Audi 90 b3 20v Looking for new gearbox and some advice

[xxErix]

Hello

So after changing every mount, every bush, etc. my drivetrain slack or shunt is still present (no where near as bad as it was, but its still there), as on more inspection on propshaft removal, definetly the gearbox is worn, and the shunt is coming from that. Rear diff etc is all good and fine. 

So I am after a 7a gearbox? or is there gearbox from other models that could potentionally be a straight fit?

thanks for help in advance
