I have heard of guys installing a np203 in front of their 3sp t-case and was wondering if anybody knows anything about it? I have an sm-420 that I want to make it all happen with.Maybe some websites or pics, any kind of info would help. Thanks

Go to ih8mud.com - there is an article on the topic there. BTW, the password to get access to that site is "cheesehead" <IMG SRC="smilies/biggrin.gif" border="0">

the adapter is made by advanced adapters and uses only the front (reduction box) section of a 203 and lets you bolt the 3spd case to it. it's actually cheaper to go this route than getting a 420-3spd case adapter. also, it's about the same length. pretty cool setup. good luck.
