These are currently £2.14 at JK - talk about cheap. My question is , do you have to drive the hinge pins in using a drift or similar. My doors seem to have play in them even with a new conversion kit fitted. This results in the door sitting too low at the bottom corner. Not helped by the fact that the hinge plates have been stripped in the past and I have had to use a nut and bolt which is tricky to get a spanner on. How can adjust the door so that the rear of it is higher? Also why are there 4 round pieces but only two pins - are there two different sizes?
