brought nissan patrol straight 6 n/a diesel:doh::alien::mil75::mil75: with conversion plate to go into my old girl but having problems the engine including mounting legs from lt77 defender is 26.3 inch width but what should the chassis be on a series 3 lwb ex-2625 want this fitted the cold is annoying my s3's gearbox

defender lt77 as used on the na td and 200tdi bellhousing is very similar to a series bellhousing if thats what you mean although i don't really get what your previous post means. They do bolt up together with minimal work unless the engine was fitted to an lt85 box to convert a petrol mabe

the defender was originally a 2.5 petrol truck cab sat in a D reg all marrige points are the same apart from the gear box i think was a 24 tooth defender type then so the clutch plate was realligned and changed for the 10spline? series type does this help us at all? i knew that the discovery and range rover and later defenders were allso wider but engine mounts really?

I think your gonna have to give us a full explanation, I'm struggling to understand that.
When you say 10 spline do you mean early 200 series drivetrains?
If the adaptor plate for the engine is made for the job then its just a case of fitting the clutch that came with the lt77's original engine, if the original clutch wont fit the flywheel then sometimes you can drill out the rivets and remove the centre boss and fit the boss on the patrols clutch plate.
Otherwise the lt77 is 100mm longer than the series box and has diffo mounts (I dont know if the lt77 box will fit the same bellend as the series box, I think it does), you'd have to fab something up to fit, and get the engine a bit more forwards to compensate for the extra length, this is why deffy's have a flat front.
Unless someones starting selling adaptor kits to fit the lt77, but I dont think so.

i think he means clutch centre but it has no relevance if you stick a series clutch to the engine to be used with a series box then no probs full explaination needed chassis sails were much the same widths up until really late models i believe

Yeah I wondered that, a series clutch may well go in.
Theres a brake and clutch centre in town here and they will re-line a clutch and also they have swopped the centre boss over for me a couple of times to make the wrong box fit the right clutch.
