203 transfer case? i was checking the page for transfer cases and to my limited knowledge i have a 203 in a 77 GMC 350 with TH350 full time front end.the page states that the 203 has no drain plug and the speedo cable on the drivers side. mine has no drain plug,the fill is in the right place for a 203 but the speedo comes in on the passenger side top right looking forward at the tranny. the 205 speedo is supposed to come in on the passenger side. where does the 208 speedo come in? most full time TH350's auto's have 203's,as far as i know. any ideas on this? Thanks.
