    Does anyone know of a good online source for transfer case ID and/or tranny to transfer case adaptors and what they fit (that would be the $hit if there was such a thing with pictures). We have a page on CK5 for axle id, but I was looking for bolt patterns on t-cases. The reason I ask is I broke my tranny to t-case adaptor and have been trying to buy one. Several people say they have ones for sale and when I look they are not the correct ones. I also was looking at them to see what combination they were to TH350 to NP205, TH350 to NP203, etc., etc..
    If anyone knows of one, let myself and the rest of CK5 know. Maybe Steve will even post a link to it. Thanks.

    If you didn't build it yourself, how can you call it yours.......?

    Did you check this site? <a target="_blank" href=http://www.advanceadapters.com>www.advanceadapters.com</a>? They have a nice table that shows what was original with each tranny and what adapters you need for other trannies.

    Hope this helps.

    I have the 4-bolt tranny mount (which is the same for TH350's/700R4's) with the "figure 8" pattern for the 8 bolt early NP205's which is what I broke.
    I also have a 4-bolt (TH350/700R4) tranny mount with a circular six transfer case pattern (for newer NP205's and NP208's).
    A guy had an adaptor that was again the 4 bolt mount (TH350/700R4), but had 7 holes on the transfer case side (I'm assuming it must be for the NP203 case but am not sure since I can't seem to find a bolt count or picture/illustration of the bolt pattern on the NP203). I looked on Advanced Adaptors website but could not find a bolt count or illustration of the NP203. If anyone has a spare TH350/EarlyNP205 adaptor please let me know.
