Marina Diff, is it interchangable?

Ok, this new trav of mine has all marina running gear. I have no problem with the rear axle, but is the diff in it interchangeable with minor ones?

Think it's a completely different beast Matt.

Seem to remember someone saying Marina diff was Triumph based, or was it gearbox.

And is it Triumph = Dolomite rwd range ?

Gearbox and back axle are Dolomite/ 1500TC based (not Sprint though) - Or the Dolomite gearbox is Marina based (I think that's the right way round for that part, the early Dolomites had a three rail, later had a single rail which I think the Marina had earlier).

As far as I know the TR7 uses the same diff, and probably other Triumphs in different housings. Should give you a few fairly cheap options for ratios if that was what you were thnking, as the same axle casing was used from 1300 up to 1850HL, with a couple of automatics in the range too
