Should be a fulltime married NP203 transfer case, unless some swapping been going on.
I think W300 back then were cab/chassis or special service beds, no pick-up truck beds.
Is the PTO ran off the tranny or tcase?

Post up a ton of pics, then we could tell you almost whatever you want to know.

Stock would be a NP435 transmission, and a NP203 transfercase. Fulltime means the power goes to all the wheels all the time. similar to allwheel drive on newer vehicles. Married means the transfer case is mounted to the back of the transmission. the other way is called divorced, where the transfer case is mounted separate, and has a short driveshaft connecting it to the transmission.

Superburb I thought the np445/203 were an exclusive thing?
Not sure what you are asking. The 203 was used by all three major truck makers, so was the 435. The 445 was optional for a few years by both Dodge, and cheby.

I misunderstood some info from someone else...I was thinking the 203 was only ever mated with the 445 in a 70s full time dodge.
I have several of both the 445 and 435 and now I’m curious...gonna need to go check some bolt patterns and shafts.

That's the info I was looking for but was afraid to ask (y)

I believe you will find that the 203 was just for 80 &81.

If he's lucky he's got the 205... heavy duty!
Was there ever a hook up for PTO on full time transfer cases? Not heavy duty. :)

Yes, both have the PTO. By New Process, both were rated the same. ;)

Good info! it is married to the tranny. I spoke to the guy I got it from, it was a fire truck. They pulled the bed off, and put it in the back 40 for the last 7 years. As far as the tcase, the pattern on the shifter has "LOW/LOC and HI/LOC, not the normal 2hi, 4hi etc...

I have seen at least 2 78 fire trucks and neither were 205s, I agree with super that was probably 80-81 when the 203s started going away. The 203 gets a bad rap on the internet but I love mine and wouldnt trade it.

Agreed, I have swapped a few 203's into 80's trucks. Getting close to dropping one in my 90.

I have never seen a married NP205 in any Dodge before 1980 model, nor any NP203 after 1979. GM offered BOTH during late 70's.

The 205 never gets a bad rap... and I'm glad my truck came with one. ;)
