I pulled the 203 out of my Sub and put a 208 in the truck. B4 y'all get uptight about going with a 208, understand that it is the best choice for how I use the truck. See Locosmocos.com for further explaination. I am going to put the hi/lo assembly with the TH400 adapter & trans output shaft on ebay. Is the hi/lo's output shaft needed for a doubler or does that have to be made from scratch ? Dang thing's heavy enough w/o shipping the buyer parts they don't need.
