I have these duals that came in a 84' 4runner I purchased that was rolled. I chopped the top off of it, and built a buggy out of it. I drove it for about 6 months with these cases in it, and they work great. Both of these cases have stock 2.28 gears and are top shift. They are dirty on the outside I have not cleaned them up very much just enogh to show the Marlin Crawler MC08 stamp on the adapter. I can ship them anywhere in the U.S. on your dime. This is a very good deal considering the kit is about the same price as what I am selling this complete set for.
