last night I said I was going to send some pictures of my 200TDI 1993 defender original condition. It's a LHD but hope it helps. As somebody said the lower hose is for an air intake on the fender in some cases to install a raised air intake (snorkel), but you can drive with out it.

I'm going to convert my 200TDi 2 door SW to a pickup and hope I dont come across to many problems. My 2 door has the rear bulkhead already fixed to the vehicle, so I would only need the pickup roof top, the rear panel and rear tailgate. Does anybody knows how sells the complete cabin?

Tomorrow I'll send you a picture, but is a Left Hand Drive 200 TDi defender

I have my install under the hood of course attach to the engine, but it's a LHD 1993 Defender 200TDi, would it work for you? if it does I'll take and send photos tomorrow monday
