There are sure to be some but a slightly less general location might bring out those who know of more local suppliers.
Anywhere in the uk or Ireland. It has to be shipped anyways so makes no odds.
Closer to norrhwest is prefer but if any good recommendation from anywhere i will take.
Also more if they rebuild with new sonnax values and pressure pump.
Also tc stall speed to be reduced.
If im going to pay for it i want it done right, not to have to to replace it again in the next 40k as it will be towing 90% of the time
