What about Pilsden Autos(Dorset) for a 2nd hand one? they are breaking one with around 30k on it don't know how much they would want for one, they are advertising on Ebay (front wiring loom ZT V8).
thats a good idea Paul. Very helpful on the phone when i brought the gear surround from them

Thank you Gents for all your advice, it's appreciated. £520 + VAT is a bit painful! :I will have to see. I am still sorting out things with bespoke at the moment. I will keep you posted.
It's a V8 thing - 031
The ones at Auto developments I saw looked new ???? or were these factory warranty returns like the first engine Martin Warner had ??
Perhaps we need to find a good alternative supplier for these, I had contacted the uk rep regarding technical issues I wonder if we could do a group buy ???
Heres some info from previous post,
Diff oil information from Dana
Ive had a reply from Dana regarding the diff and the recommended oils that can be used,
HI Geoff
Your below email has found its way to me via the USA and Australia.
It is good to learn that there are still enthusiasts for the MG ZT260, I was the DANA Australia?s UK engineer for the MG project, I also looked after: - TVR, Aston Martin, Marcos and still manage Morgan Motor Co account.
Answering your question is not straightforward, the limiting factor for the final drive unit is the amount of torque it experiences and how many times it sees high torque loadings. The torque is either the max engine torque multiplied by the transmission and final drive gear ratio or the ability of the tyres to transfer this torque to the road before slip occurs. The numbers of experiences of high torque loading is in the driving style and/or the load generated by the vehicle, i.e. trailer towing, hard acceleration, high speed driving, track days etc.
To sum up high torque loadings bend the gear teeth, as with any material it will only bend and recover so many times before reaching its full life at which point it will fail. In racecar applications, teams will often replace the gearsets based on a set life, thus avoiding a fail.
There are only three oils available in the UK that have full sign-off for the unit. These are:-
Mobil SHC80W140 id
Castrol SAF-XJ
Morris Lubricants Lodexol XFS 80W-140, this is my preferred option as it has high concentrations of friction modifier and is available if small pack sizes.
Rebuilding the units is not straight forward as the gear tooth contact Patten is not what most UK transmission re-builders are used to, However John Reid of Grantura Engineering http://www.readmanracing.co.uk
As TVR?s ex race team manager has a lot of experience with these units and carries many of the parts.
If you require any further information please call or email me.

Depending on price we could buy two or three, one could stay with Phil up north and one with either me or Justin in the midlands & south. Boils down to cost if we blow our bunce on two or three high cost items we would need to build up the reserves again. Where do you stop props/subframes/engines?
Perhaps the best way is to identify 'friendlies' where we can get our hands on the bits. In the long long term I would be trying to get MGOC to position themselves to cater for our needs like they do for the classics.
