hello everyone my sons got a k11 that i maintain for him hes had it for 3 years and in this time ive replaced the front cross member both cv joints and seal clutch and a bit of welding on the rear seals, so all was ok until he said he has a water leak coming from the rear tailgate on to the backseat when i looked the panel that the tailgate hinges bolts too is rotten so my question is is there a replacement panel available or will i have to make one ...thanks browny
