Not easy to find
I have 3000 on it now

Got the 203/205 doubler from Tate.
It is set up with 3 shifters.
Let me know if I am right on this:
Shifter 1 controls the range box. Just two positions, engaged or disengaged?(hi/lo)
Shifter two controls the rear output. Has 3 positions, hi, neutral, low?
Shifter 3 controls the front output, has two positions, engaged or disengaged front axle?
It looks like my trans crossmember will not have to change. T-case skid will prob need to be redone, but there is a chance I can just slide it 4" or so down the frame rails and reinstall. This depends on if the 205 hangs much lower thatn the BW. The skid right now is very tight to the BW. Running a couple tubes from the trans xmember back to the skid to create a skid for the 203.
It is very heavy. I see the machined flat spot on the side of the 205 with 3 holes. Can I just make a plate for that, which would bolt on, then run a tube or some sort of 'arm' out the inner frame rail.
With the front engaged, the rear disengaged, and line lock holding the rear brakes, a full detroit, can I do amusing campground circus tricks?:D
Running a brace to the frame off the side of the 205 is deffinately a good idea. I am running one on Pigpen after breaking 3 TH400 housings. It seems to have fixed the issue.
the front output shifter should have 3 positions, low, neutral and hi, depending on if the rails were ground or modified then you can put the front in low with the rear in neutral, if this was not done i would recommend doing this as it makes making tight turns easier on the trail
It is done. Shifter 1 range box. Shifter 2 rear output H N L. Shifter 3 H N L. You have to shift 2 and 3 in a certain order to get in L L because the rail limits from front being in H and rear in L and vice versa.
OK, I have been playing with it some more. Problem I am having is that I can not get it in 4hi. The rear output will not go into the HI if the front output is engaged. Consequently, the front output will not enage if the rear is in HI.
IF the rear is in neutral, and the front is engaged, the front stays in LO. Is it suppose to have front HI only?
Oh and range box has H N L too
You should be able to do hi in front, rear, or both. Put all 3 shifters in neutral, then try to start putting it in hi.
For install, on the klogger I cut a 2" X 2" hole in the floor then ran a chain with a come-along to the case to pull it up. It made it a lost easier.
on 78ish fords there is a stock rubbber mount for the 205.
Thanks Tate. I got it figure out now.
The front output has to be in neutral then shift the rear to HI, then shift the front to HI. Its preventing HI in one axle, LO in the other.
Does it have fluid in it? Did you just silicon it all together? It will prob be easier to take it apart and install a piece at a time.
Going to probably wait till after TCC to start putting it together
Make sure you fill both cases, The 203 and the 205, they are not joined together.
Thinking about it some more, I need a x-member that attachs to the ORD adapter. Looks like it has two threaded holes there already.
Both cases are empty right now. And it will not be easier to install one at a time because you won't have the space to bolt them together. Eric and I put it in using a rachetstrap and a lot of effort. I like Karl's idea though.
When I get home I will post some pics of my cross member.
