|big gear head||Randy's Ring & Pinion has them at 2 of their warehouses. They had the best price that I found. They also might have some kind of limited slip differential. I didn't look into that. Contact Bruce at extention 5517 or Jim at index.jpg. Jim might give you a better deal on them.|

Can you tell me where to go for them?

|big gear head||I did some checking and I was able to find a 3.38 gear for this rear end. I don't know of any limited slip differential for it, but you can change the gears to something that is a little better on the highway.|

There just isn't many parts for that 9.375" 55T Rear. No aftermarket Posi Carrier.
A complete Rear swap, GM 8.875" 12-Bolt, GM 8.5" 10-Bolt or 9" Ford would be the best option.

|beachbum0||Hy, SSedan64 Thanks man, went to that link,will give them a call. would be nice if thay had limited slip to drop in, look's like the same and it was my year. Even if I had to fork out the dollars for a hole pig, it might fit onto the tube's. thanks againe|

Well I will just keep looking because it's under the truck so well. I would hate to start cutting and welding. Thanks for the help, maby someone will see this and have a solution.

I forgot to add, the axle is in place and I would rather not have to make another fit . By checking, it's a open rear and would like a limited slip.

|big gear head||I don't k know of any parts that are available for that rear end. I just don't have any experience with it.|

the make of this rear
Insted of a swap, can I make this differential into a limited slip? And if so, can I change the gear ratio ?

Only aftermarket ratio I've seen available is 3.38
GM 55T rearend.

That's the old truck rear end that was used from somewhere in the mid '50s. Sorry, I can't tell you much more than that. I haven't been into one of those before. My brother has the same rear end in his '57 truck. I think it was replaced by the truck 12 bolt around '64.
If you only turned one wheel then you only got half of the gear ratio. If you leave one wheel on the ground and turn the other wheel exactly 2 full turns and count the number of times your driveshaft turns that will be your gear ratio. If it turns just past 4 times then it's a 4.11, if it turns just past 4 1/2 times it's a 4.56... Those old trucks usually had gear ratios in the 4s.
A popular swap for those rear ends is the '67 to '69 Camaro or '68 to '79 Nova rear end. I'm pretty sure that those truck rear ends are right at 60 inches wide, which is what the Camaro and Nova rear ends are. This will also get you the smaller 5 bolt pattern for the wheels.

The make of this rear end
Finally i was able to upload pictuers can someone tell me what this rear end is so i can get the cover off and get a gasket.
|07-14-2012 05:17 PM|
I just marked the tire and the drive shaft the driveshaft turned two times around for almost exactly one time around for the tire, can this tell me anything about the gear ratio.

|beachbum0||do you see the pics in my profile? What is the rear end make ?|
