Who makes the best  transfer conversion kit  for a 203 in a 3/4 ton chevy? mile maker or superwinch or is there others? I saw some where there is a better set of instructions anyone have the link? I already have lock in/out hubs. has anyone tried synthetic oil in the 203?   sorry for all the questions, first time to have a 203.   thanks

I used a MileMarker kit a long time ago. I never had any trouble with it. All I remember about the install was that it was simple. Almost 20 years ago when I put it in. I used the truck for a street legal mud bogger and was very pleased with the product. I broke about everything in that truck atleast once but not that 203 with a milemarker kit.
