The Stovebolt Site Forums The Shop Area Driveline 53 1 ton panel rear end swap

hello, what new-er 3/4 ton rear end will fit in my 1953 1 ton panel ? going to use 292-6 with 700r od trans .

The easiest would be to find the 4.10 3rd member from a '68-'72 3/4 ton, as it bolts right into the stock rearend housing. Unfortunatly, those are difficult to come by. If you don't mind doing the fab work (manly welding on new spring seats), a rearend from an '80s Dodge/Ford 3/4 ton van (Dana 60) will fit just fine. A 3.55 ratio is common in those. You'll want to watch out, though, some of those are semi float instead of full float like the original axle. For somehting that's just going to be a driver, semifloat will be fine. But if you plant on loading it, a full floater is better.

A 14 bolt rear axle from a cab and chassis Chevy (was dual wheel but run centered singles on it) is also another good option. If you swap it to disc brakes it fits real nice, if you want to keep drums that can be done too with a little work.

I'm with Grigg on this one too. The 63" 14 bolt is by far the easiest to come by. Trust me, I've been crawling around junkyards for the last several years with a tape measure. Finding a Dana rear out of Dodge or Ford van is just about a lost cause. I've only seen one Dodge with the narrow Dana in about 5 years. I've seen a ton of Dodges with the semi-float 9.25" though. Same with the Fords, I actually have yet to even see one with a Dana. Most likey you'll be looking at a Sterling semi float or full float Sterling. Trying to find a 67-72 center section is futile also. Even if you find one, the best gear you can hope for is a 4.11. Get ready to write a big check too, it won't come cheap.

I have pics of a couple 14 bolts. One is a 67" and the other a 63." www.photobucket.com/whitedog76pics I got both of them for $300 on Craigslist.

Hello-thank's for all the info - found a 1970 3/4 ton rear end-need to ck out 3rd member gear ratio.

Those 4:10s were in the trucks with automatic trans. I found mine via a 'wanted' ad right here on the bolt, best thing I've done to help the old 3/4 ton flatbed of mine.
Those trucks are still on the road all over CA, not as popular as the half ton, usually cheap. You may be able to buy a beater with the rear end you want and swap gears and resell.
Best of luck

"Those 4:10s were in the trucks with automatic trans."

A popular bit of folklore, but not entirely true. Auto transmission and coil sprung rear is the most common configuration with the 4.10 gears, but they were found in other trucks as well. I pulled my 4.10 center section myself, and it came from a manual transmission truck.
