you are just be lazy with the auto trans.

I can see your point though. I was thinking more of the gear ratio split from granny to 2nd you mentioned you did not like granny as it seemd to low and 2nd was a little to high to pull off from a stop all the time...this does make driving one a chore and gets old. But when it is geared just right it is a breeze and better mpg for a 4x4 IMHO.

mine was a blast in low range 3rd gear 6200 rpm turning 4.56 gears and 17/40/15 hawgs in the mud pit up to door handles.

BUT my auto never would wind up fast enough and did not spit u-joints like the 5 speed did either.they do indeed have their pros and cons.

I should also mention that I do a lot of stuff around the yard with the truck, getting in and out frequently. The parking brake sucks, so the truck wants to roll. The "Park" feature is quite handy for what I do.

another pro for auto

that is not being lazy, that would be being safe.

To swap to auto from manual, don't forget to change the radiator (no trans cooler in a manual truck radiator) and run the trans lines to and from the radiatior. You can use an aftermarket floor shifter so that you don't have to swap the steering column for a column shifter, pretty easy.

Keep the NP203, nothing wrong with it and the best Fulltime 4wd case from the '70s, by far (I currently have two of them).

I have an extra BB auto 4wd truck that I'd like to sell, as well, but I'm in IA and probably a little far for you...although it would have all the necessary parts for your swap...

No need to swap radiator just get a trans cooler. I've swapped in a stick Rad in an auto truck and used an trans cooler. No issues.

Got pics of the truck? I'm just down the road

"Got pics of the truck?"

Sure...

I still need to add the yellow stripes to complete the "Macho" look.

Looks outta my price range

No rust at all on this truck...the oil leaks provided a nice corrosion resistance!
Kidding, of course.
The yellow stripe kit is being reproduced. I do want to get the kit but I've really spread myself thin with all of the projects here. I don't list my cars or trucks, but along with this 75 PW, I also have a 78 Trail Duster, a 2007 Ram 1500, a 65 Barracuda, a 67 Dart GT, a 71 Duster, 73 Swinger, 74 Duster 360 and this:

In Iowa, if it doesn't have rust it's A) been restored, or B) it's not from Iowa!

I painted the truck here in my garage. part of the reason that I've yet to install the "Macho" stripes is that I'd want to cut and buff the paint beforehand.

I am not too familiar with the correct years that I should look for in regards to a donor transmission. I have a good passenger car BB 727 so I'll be on the lookout for a 4x4 trans to get the tailshaft and other associated parts to swap. I know I'll need a trans that fits my 203 Full time case. I guess I could just look at the front end of the trucks, making sure they would have that large nut instead of a part time hub. The local yards out here have an online inventory list and even though it is often innacurrate, it does help some.

If you were closer We could do some horse trading

75-79 4wd's were all fulltime so that's what you will be looking for.

you only need the tailhousing/main shaft off any 727 small or big block----you already have the hard part---the big block case..... bob
