Thanks Gentlemen.

It's funny how there's pockets of information out there and you can look for months chasing down cold leads, shift a little and run into a whole bunch of people that have already been there / done that. :0)

I have a 1949 4400 with 6.17 gear ratio. Any suggestions for my situation?

Speaking from the perspective of an old dirt track racer who used a lot of those HO72 4.10 gearsets back in the late 1970's (one reason they're so scarce now), the ring gear carrier has a different side spacing, so it must be changed along with the ring and pinion. If you can find the Detroit Locker center section as well as the gears, grab that, too. They're a little noisy in turns, but in a slippery situation, the pulling power is awesome.

AlexJ in Virginia helped me change my 1953 3600 from 4.56 to 4.11. Took under two hours. He sometimes has one of the center sections on hand, and has done the swap many times. If he has one, he can ship it at a reasonable price and talk you through it. You might want to PM him. Just a thought.

I have a chevy 3600 1953, and I want to change the crown and pinion differential to 4.11, to get more speed. They know site online where I can buy them?

I have the same truck as Juan and I have the same question. Where can I find a third member from a 69-71 Chevy pickup? Any suggestions?

I have an identical truck. sorta. I have a 51 3600 series 3/4 ton. I took the complete differential from a 72 3/4 ton and installed it. 3:55 ratio. it's a bit wider and I had to open up the center bolt holes a bit, but i'm very happy with the result. 70 mph with tall tires and a 235 engine.

This is one of the best links for finding a pumpkin.

Ownster.com

They throw craigs list, Ebay and a few others in your search results. This is how I found mine.

Also don’t just try to find the pumpkin. Rolling chassis‘ are also a source. Just ask for the pumpkin. That’s what I did. Find someone selling a frame or part of a truck. And don’t let anyone here kid you. They are hard to find unless your in the north.

Can’t begin to tell you how much I hate the name Stovebolt.
