Kia Ora, I am Chris, a newby and would like to get some information from the experience of others. I have been a self employed Auto Restorer for the last forty years. I have purchased a Nissan Mistral 1996 R20 auto transmission, the main purpose of its use will be to knock a bush track uphill approximately 200 meters to a building site approximately 500 metres from the road through thirty year old regrowth of manuka and ginger plant. I have mounted a 5000 lb electric winch to assist and thought a set of chains on the front wheels would help, I don't want to change tyres to muddies as normally I will be driving 450 kms there to work for a short time and then back home. I pressing matter first, after reading on this model I have found there is a usual problems with rust around the rear seat belt mounts, any pictures or information regarding repairs would help. I have a water leak on the LH side front floor, is there a usual place to start looking for the ingress, I have checked the plenum panel and found water leaking around the sealing washers holding the fan and rust proofed with Lanoguard to seal further.
