who has some pics of these together? also would like some pics of a 203 mounted to a 700.
I would really like to help you out but sorry I have no pic's maybe someday.
I don't have any pics, but I was running a 700R4 connected to a NP205 forawhile. I had a AA output shaft installed in the 700R4 when I had it rebuilt, this made it exactly like the TH350 as far as shaft stickout goes. Then I just used the stock 205 adaptor with the coupler sleeve and bolted it up. Even, used the same shifter for the T-Case, however it did move back slightly in the opening. Just had to clearance the floor tunnel a little.
I dont have any pics but ive got a setup for sale.
700r4/205 with adapter and shifter if your interested. /forums/images/graemlins/ignore.gif
do you remember how much the AA adapater cost ? i have heard they run about 550 . also what is the coupler sleeve ? i have a 205 with a adapater but no sleeve
What vintage of 205 do you have? Mine was a 78 version with a figure 8 bolt pattern for mounting the adapter. My 205 had the 27 spline male input shaft (TH350 version). After changing the output shaft of the 700R4, it made the rear of the 700 just like a TH350. Then I just reused the coupler sleeve and the factory adaptor. There are a couple of different coupler sleeves used. One was for the 4 speed to 4speed version 205, which is a course 10 spline and one was for the TH350 to 205, which was a fine 27 spline. You need this coupler to mate the two shafts. If you have a newer version 205 with a round 6 bolt pattern I am not sure what you will have to do. Check out the ORD tech page. ORD Tech Page
If you have a 205 off a 350, it will bolt right up! All you need is the adapter shown in my web page! The 205 has to be from a th350 Tranny! There is no way to adapt another style 205 to a 700! The output shaft from AA is about $650, and then you have to rebuild you tranny! The adapter in my pictures is $60 to your door from a tranny shop in another state! At least that's what I got it for! If you want the Name and Address, try a search, I just posted this last month to a guy!!!!!!!! Later!
i have a 205 its out of a 69 k5 . what i am wanting to do is this swap to where it looks factory. the shifter i have is also out of the 69 i dont think it will work so i would like to find a shifter out of a later model also the front output needs to be changed to a flat 4 bolt flange . i have thought about a AA shaft but they cost too much. and if i buy a spacer i think that would set the shifter too far back and my driveshafts would have to be modifed and i dont want to do all that. so i guess i need to study this a little harder before i try this but i really need a overdrive

I'de say no matter what you do the rear shaft will have to be modified. Not sure on the front shaft though.
The Advance Adapter kit is only a new output shaft. The part number is 50-6900 and the cost on the AA site is only 170.75, which means you can get it from a distributor for much less. I only paid 150.00 for mine. My 700R4 needed to be rebuilt anyway so no big deal. The change in length is about 1-1/2" due to the fact that the 700R4 is longer than the TH350. My shifter came out it the factory hole with only slight trimming. I used a factory 205 shifter boot and mounting plate. Hope this info helps.
You might want to consider moving the engine crossmember forward to account for the extra length. Would require no driveshaft mods and the shifter would be in the original spot. I've heard about it being done on a first gen but not sure what your working on.
i am putting it in my 79 k20 . if i can buy the adaptor that goes in the transmission for 170 thats the way i will go.
there is an spacer type adapter you can get from transmission supply comps. I have a part # laying around somewhere..I'll post it along with a pic if I can find it. Thing costs around $50 if I remember right and all it requires is the shaving of about 1/8" off the 700s shaft.
