My gearbox is an 1b5 i think it's out of a p reg non turbo escort diesel van as turbo diesels run mtx I think

I had to use a diesel one and because the starter is at the front unlike the mark 6 escort gearbox where the starter is at the rear on petrol models

I think the only reason it hasn't broke yet is because I think the shafts are breaking before the gears on my last outing at pod I ripped a vibertechnic mount in half

Also I think the main shaft bearings are bigger in mark 6 boxes so this may help
