First, Welcome to the site!

Second, we're not clairvoyant.  If you want help you have to tell us what you're working on.  And, then actually pose a question or problem with which you want the help.

     X2 on above.  I guess you have a 86 C10 by your signature.  And let me play, you want to take your axle and turn it into what is in the link and you want us to help you ?  Or asking if this axle will work in your truck ?

well in trying to find out the drum to drum width and the spring perch center to center width so i can build the street truck

Can we assume you don't have the OEM rear end to measure?
Do you still have the springs mounted on the frame? If so you can measure them C to C (center to center) That should be the same as your spring perch C to C. Once you have that, the distance between backing plates doesn't have to be the same as stock. (Within an inch or so) This could be a good time to figure out what wheel and tire combo you want and build the rear end to match.

No I don't have the OEM rear. but i got something better than my shortbed .....I've picked up a 86 GMC Sierra longbed. I recently put a TH400 in it but i need to get a longer driveshaft. I'm gonna run 15x12 in the back and 15x6 in the front. but now some of my friends say i should lower it. witch direction should i go now?

     So just to clarify, you are looking for the width of the overall axle and spring perch location center to center correct ? 
     Just a question, did you pick up the 86 without a rear axle ?  Otherwise it should have the stock axle in it. 
     More information please.

Yes bake74 thats what im looking for. and it didn't come with a rear axle.

     OK, so now I understand.  I do not know if you knew about the GM Heritage website that we have a link for in our tech section, but here is the address.   http://www.gmheritagecenter.com/gm-heritage-archive/vehicle-information-kits.html
     Unfortunately I did not see the actual measurements you are looking for, but they have about everything else.  I am going to pm somebody on here that has a 85 and ask him to look at this thread, maybe he can measure his for you or just know what his is .

I have a stock 10 bolt 2 wheel drive rear end from a 1986C10 I will measure for you.  It won't be until Saturday sometime.  I travel for my job now and am only home on the weekends
