how rare is it to come across a np205 transfer case in a mid 70's blazer mated to the th350? seems as though most have the np203. was it something you had to special order?
Yes they will be available soonkind of hit or miss I guess. I have seen lots of th350/205 combos and th350/203 .
welcome to the site . and I like the rims on your ride in your avatar . are they true western wheel brand ?

I am pondering doing a swap. i have done some reading on what i need to make it happen but I may wait a while. I may buy the pieces one by one and just take my time getting it together.
How difficult is a twin stick modification? What advantages to I get from that?to here this from me is rare . . . . .
a good working 203 with conversion kit done only needs a twin stick shifter mod to make it perfect . offroad design make them .
there is no real advantage i have seen . unless your chain is streched and needs a rebuild and you have ALL the parts to change it . even drive shafts need swapped for length diffrence .
900 to rebuild the 205 ? if so you got hosed big time. there stupid easy . did you see my build thread in the article section with TONS of pics and step by step . https://ck5.com/forums/threads/4l80...05-ord-doubler-3-sticked-its-all-done.253000/
