So... if I go through with the Mogs, I will need to get a drivers side drop tcase.

What is my most economical way to do this? I looked quickly to find a T350 to Ford 205 adapter, but came up short.

I am not stuck on any trans yet... but, has to be an automatic.

I will have to sell off my doubler setup, and will probably just go with a trans and tcase, skipping the doubler the next time around to save some money.
 
If your dumping the doubler , you can do a np241 from a early 90's IFS rig with a 4l60 ( until 93 when they went electronic tranny ) , a lot came with a shifter setup and no auto bs on the case . By the 90's the automatic overdrive tranny's had all the updates too .

Otherwise , all the heavy hitters sell a doubler setup for any 203 to any 205 .

I see it costing a bit either way , especially when you consider your time is got a to worth something too ( you can't ever get that back )
 
I guess I could do a doubler set up again. I hate to compromise what I ultimately want... I just know this is going to get expensive real fast. :-)
 
Yup , it gets expensive , but thats the name of the game when you really start getting into the wheeling side of the hobby .
 
I have a left drop divorced type 205 from a 74 F250. Just what the Dr ordered. To bad your so far away,shipping would kill ya..

Thanks for the thought.

I can get a Ford 205... but it wont mate up to a GM trans. I looked for an adapter that would allow this... but haven't had luck. This would be the easiest and cheapest way(depending on the adapter).
 
here you go drivers drop 203/205 with a hp 60...its either that or whats said above...you could go 241/ford 205 doubler or get a stak or atlas :eek1:...

What engine are you running? What trans? What did the 203 come out of? Thats a Ford 205 I am assuming?
 
i dont have this truck anymore but it was

350 tbi
700 with a spacer
dodge 203 with a chevy 27 spline input
the dodge case was clocked which is why the mounting foot on the doubler adapter is not flat
yes its a ford 205

What doubler adapter were you running?
 
ord everything including the cases came from them...i sold this setup to b454rat a while back and he was trying to sell it you might wanna pm him
 
The Ford, GM and Dodge (and even Jeep) 6 bolt round patterns are the same, so any 6 bolt case will bolt to any 6 bolt adapter.

BUT, they aren't always clocked in the same position. The round pattern isn't symmetrical so it can only be bolted up one way. For instance, you could bolt a Jeep 6 bolt t-case to a chevy adapter but it will be 90 deg off (i.e. the transfer case will be pointing straight down). I believe (but I'm not sure) that GM, Ford and Dodge use similar clocking, but that's something to watch out for.

If you use a Ford 205 you are limited to either the 31 spline (stock Ford) or 32 spline (relatively rare Chevy) inputs.


A 241 from an IFS truck would be cheap and easy but then again its a 241. But hey, it might survive upstream of that 7.56 final drive in the 404 :pimp:

I am not real up on the 241 idea. I dont think it would last with a big block, minimum of 44s.

And the Mogs I should soon have are 406s. :D

I was told by ORD that the current doubler set up I have will not work in any way to get a Ford side drop. I would have to replace the doubler adapter for sure.
 
I "think" if you get a round pattern ford 205 with a round pattern Trans you can redrill the 205 face to match the trans pattern with the ford case.

Drill and tap new holes, plug old holes and mate it up. You might even find that some of the holes line up and only a few nee redrilled depending on the clocking you want.

Not sure about any of the above but it seems that this is one way.
 
He's suggesting that if you get a TH350 to (any round pattern Chevy t-case) adapter, you can make it work (which I forgot about). Are TH350/205 adapters round pattern or not?

Anyway, basically you take the adapter and put it against the Ford 205. Clock the 205 however you want it, then mark the holes in the adapter on the 205 (at this point, if one or two holes in the adapter are close to the holes already drilled and tapped in the 205 you can clock the case up or down a bit to reuse them). Then simply drill and tap the marked holes you made and voila, a Ford 205 behind a Chevy adapter. Also, you may need to plug a couple holes in the 205, some go all the way through the casting and some don't.

Of course, this all comes back to a 27 spline TH350 with a 31 or 32 spline 205 behind it which is another problem.
 
I currently have a TH350 203 205 doubler.

This might be my best bet to get it working the 'most economically'

Is this right?


27 spline TH350 output to 27 spline 203 input

32 spline 203 output to 32 spline 205 input


If so, you can put that 32 spline input into a Ford 205 and run it (assuming the Chevy and Ford 205's are clocked in a similar fashion). You kinda made it sound like Stephen at ORD didn't think they were clocked the same, if that's the case, you would need to do what miniwally and I described in the last few posts (or use a clocking ring if you're lucky).

I am a little behind on just what cases come with what splines, etc. But, I did talk to someone at ORD and they said I could not just simply swap the t-cases. So, I would guess that I would have to do the drill and tap thing.

Clocking ring... ugh, I am so behind on this stuff. I know what a clocking ring is... basically allows you to rotate the case. Right? I remember ready about it and it allows you to ring it up higher, etc. But... this may also allow me to rotate a Ford 205 to make with my current doubler... maybe?
