WTB: Close Ratio 435

[Greg Coffin]

Looking to buy a close ratio 435 for my 6x6 Power Wagon project. First gear in these is around 4.5 to 1. The closer to Denver the better, but willing to consider any offers.

Thanks,
Greg

How about an NP445, a close ratio box with synchro first gear? I don't have one mind you, just food for thought.

[Greg Coffin]

My understanding is that the NP445 is a fair bit longer than the NP435, probably too long to fit into a WC63 chassis without moving the transfer case backward. If I'm wrong about that, I'd like to know.

There are variations of that NP 435 transmission. I have one that is from a 1969 w200 crew cab. It is a close ratio . The input is too short for the 61-68 hydraulic bellhousing. It also has a tail shaft. Wonder if you can swap the internals into your transmission. I am in south west PA

The close ratio NP435 and the NP445 were offered
in [at least] '70 & '71 Dodge Sweptline trucks. These
had 23 spline input shafts.

I have the tag from the transmission it is dated 10 28 69. and stamped DL 75B/ 435 I guess the truck could have been a 1970. Interesting

As long as they have the same first gear ratio, the input shafts will interchange.
