203/205 doubler ingredients

[shadowjeep]

cool, sounds good. i have been wanting to rebuild a 727 that i accidently burned up a while back. that will give me a chance to kill two birds with one tranny.

Here they are. I really need to clean up the output shaft & oil it!

[shadowjeep]

thanks for the pics, that helps a lot when going to the boneyard to find a tranny. what years should i look for on the dodge tranny?

is the dodge 203 the only one that will bolt up to 727? what about the gm 203? or is that the same thing?

[McRoth]

I believe the mid to late 70's dodge's came with 203's, at least some of them. I got my output shaft from the tranny shop that did my rebuild, you should be able to find one that way too, I'd think. it was on ly $20.
Yes, the dodge is the only one that will work AFIK.

Well, the Ford NP205 is a 32 spline unit if I remember correctly, and it drops down on the driver's side. You'd have to figure how to mate a Ford NP205 to your NP203 of your choosing.

I picked up my adapter from a guy off of Pirate named Dirtybird, his stuff was inexpensive, and he made adapters to fit different 203 range boxes to lots of stuff, even Dana 300's.

The ford version has a 31 spline input, and 32 spline outputs. I would call around to the diffrrent doubler kits makers and ask if they make one where you can use a ford 205 with a chevy 203 range box

thanks for the info!

Everytime I read this thread it gets more complicated. I want to do the doubler behind my 727 but it sounds like now I have to swap parts off of a dodge 727 to start with. might as well go Black Box or Klune or just go atlas and be done with it.

if you've got the money I would. doublers are for folks on the cheap.

As broke as we are right now everything is just a dream anyway.

NW Fab can match it up for you. Any 203 with any 205 and they probably have other combos.

I finally got mine clocked where I need it. Kind of a bugger to do the clocking when it's installed on a rig but the 3" body lift made things easier. I have it so everything.... everything including the crossmember stuffs up under the frame and I have a cutout to drop the front driveline down through the crossmember.

I don't know about this being cheap, cheaper probably. Where is the challenge of just buying something in a box that takes six bolts to attach? Besides, with the 203/205 you have two places to run a PTO off of.

I'll be running a Dodge 203 and a Ford 205 in Crom soon. I got the adaptor from http://www.sumnermachine.com John and his wife were really nice and he started on it as soon as I called, so that when I made the second payment to him he had it boxed and ready to ship!

[Elliott]

Glad he's back in gear...


I've got a TH400/203 and a '90 NP205 listed in the forsale section if anyone is interested, also up on ebay. I can work it to piecemeal it depending on what someone might need.

I've updated all the dead pic links in my posts. Now, who's put a GM NV4500 to a 203 range box?

I've mated one to a GM six bolt NP205 with some clearancing and a short input (as posted in my dually thread at: http://www.ifsja.org/forums/vb/showthread.php?t=83955 ) so wouldn't this work the same as how I studded the GM NP203 case to match up with the Ford NP435 I did earlier?
