    Has anybody done a NP246-NP208 swap? I really want to do one to my 99 tahoe. I hate the electronic tcase, and I already have the 4.56 3/4 ton chevy axles, so it seems like it would work well. Anybody know what might happen to the tranny operation with no signals from the transfercase? Also on the 99tahoe where does the speedo come from, the tranny or the t-case? My 208 is a mid 80's right hand drop. Any help or direction would be great, Thanks-
