hello just wondering if someone can help , ive got a fiat ducato 1989 diesel motorhome , somewhere along the line someone has replaced the engine and gear box with a latter model engine ,it was a 2.5 and now it is a 2.5td from maybe a 91/92 model, the trouble is my gearbox keeps sticking in gear and the only way to free it is a partial engine strip so i want to replace it , does any one know if a talbot gearbox will fit this model and is there any way i could find out exactly what engine/gearbox is in the thing at the moment , cheers paul
