Help Identify My Rear, lol

I bought a 2003 Silverado and decided to buy a Detroit TruTrac for it because I was having serious traction problems at the track. I did 18 sec in the 1/4 spinning the whole way, lol. DR's helped a lot(13.9 1/4) but still some wheel spin so I can't hammer it.

Any ways, I went online and ordered a DTT for the Chevy 8.5/8.6 10 bolt assuming that is what I had since they come standard on the Silverado. Problem is my truck is a foreign(Mexico) model so it has a different rear end(Latin rear ohh great now I am thinking Vida Guerra). The shop that was going to install the DTT told me that I did not have a 10 bolt but a Dana. They were not sure exactly which one only that it was smaller than the 60. I ended up selling the DTT to a member on PT.

I looked online and it looks like a Dana 44. I went to another shop and they said it looked like a Dana Super 44 and in order to get a Posi in there I would need a c-clip eliminator and a bunch of other stuff. It would cost about $1600-1800. http://www.ls1tech.com/forums/images/smilies2/turd.gifhttp://www.performancetrucks.net/for...es3/ripped.gifhttp://www.performancetrucks.net/for...r_banghead.gif

Can anyone here tell me what rear end I have? And if I can get some sort of Posi in it?

Here are some pics.

I don't know where it was made but it was purchased in Mexico. I think it was assembled here and exported there. But they were manufactured with that in mind so they are a little different then the ones for sale here. It is considered a 2500 over there. The differential is different and the brake system, suspension etc.

I am trying to get away with just putting a DTT in it rather than buying a 14 bolt. I was told to look for a Silverado SS RWD because they came with the 14 bolt.

BTW, I found this one "Semi floater 14 bolt 6 lug chevy differential from a 1991 chevy truck". Would it work? Supposedly the Avalanch and Esky also have a 14 bolt but the suspension is totally different.

looks like a 44 to me, but i could very well be wrong

This might tell you what you need to know!

Thanks,

I used a diagram just like that from a 4x4 site and looked for the numbers. I wrote them all down and have been calling all the differential shops in Southern Cali for the last month to no avail. Actually, I have one shop that said they can get something for it but I don't want to get my hopes up until the open her up. :whack:

It is a 1500 in the USA but the sales documents show it as a 2500 in Mexico. It was built in the USA and exported to Mexico.

All I can tell is that it's an 8.625" ring gear with 3.73 ratio. I can also get every GM part number for all the internals but nothing I have access to tells me what manufacturer it is or what model.

Thanks,
That is what my local dealer said also. They also mentioned something about "American Saginaw". http://i47.photobucket.com/albums/f1...LLR/idunno.gif

One of the many diff shops I contacted thinks they have something. I am going to drive over there(two hour drive) to check it out. :giveup:

use the one from the 91.it should be alot more reasonable and stronger thean yours.i just installed a 14 bolt from a 95 pickup in mine .i did have to move the perches out 1 inch on each side and go to drum brakes ,but that was easy ,and i think the drums stop better.but i got the rear for 600,verses 2k plus for a newer ss or vmax rear.
