T221 to NP205 swap guide
This is my guide/experience with swaping the Rockwell T221 for an NP205 in to my 1969 K20.
1) NP205 transfer Case w/ adapter. Adapter shape varies depending on your transmission. My Trans is a SM465 so my adapter is the figure8/ race track/ peanut .ect shape, people have different names for it. I put new gaskets and a coupler before putting it in.
