Hi, Jmes, need some info,and can,t seem yo get anywere on the range rover section, anyway i have just purchased a 1986 range rover vouge with a 3ltr mazda/perkins 4cylinder engine fitted through an auto box, on driving it home i got the feeling that it probably wouldn't pull my caravan, so i have had the thought of fitting a 200tdi engine amd manual box, would you know wich box would fit, i have a disco box lying about would that do? sorry to p/m you but i thought you would be the man that could help me, thanks, Pete
