Hi, I’m quite new to all this stuff. I’ve bought a roof and side panels off and older version defender to put on my 2014 puma. Now want to fit a rear door, will I have problems finding a door that fits sp do one but it says for 02 models and older?Will this be a problem or do all doors generally fit and will have to adjust a bit ?

The later Puma door is different in that the window shape changed. I recon tape measure is your friend here. Find some other Landy's and check. Best to ask owners first.
