Thanks for the help, i have decided to keep my 300tdi and do a chassis up rebuild so i will be getting a recon gearbox. I was going to get a second hand box to put in and then part ex my truck for a newer model but have decided that i like my old truck and am abit worried that the newer defenders are maybe to advanced for my limited mechanical skills. I'm just priceing up bits at the moment but am looking at spending about £4000 on a DIY refurb and hope to have a truck that will last me a very long time and still cheaper than a new truck. I'm sure i will be asking for plenty of advice in the near future, so thanks in advance.
