Hi everyone, Thank you all in advance for your helpful suggestions.
I have an open 8" with 3.00 gears and i want to put a posi in it. I have never rebuilt a rear end before, but i am very mechanically competent other wise. I have found an auburn posi unit for $380.00, and a posi 3rd member for $1,000.00, what should i do? Do you think i can rebuild the 3rd member my self?
Thanks again in advance

I am not sure I understand what you mean by a "posi 3rd member". And the price for the Auburn seems a bit high to me. Do you mean the axle tube and axles? I might look at going to a nine inch if I was going to spend that kind of money...let me know.

What i mean by "posi 3rd member" is a carrier/ center section that is complete with gears and a posi differential installed in it. This would only be the 3rd member/ carrier/ centersection, i would still be using my old axle housing and axles.

hotrodman

you can get from moser allreadt set up with your choie of gear ,,log on there site never mine the site is wrong have to look up at home

Ok, I thought it looked a bit expensive. Check out this site http://www.dutchmanms.com/pricesheet.html#Anchor-65126
I bought from this outfit because they are local, but as hotrodman also said, Moser is a good supplier. http://www.moserengineering.com/ or Currie http://www.currieenterprises.com/.
Based upon Dutchman's pricing you can get a fully assembled set up for pro street for $1330.00 with a Strange Nodular case and 31 spline axles. I am sure they could do it for an 8 inch set up even cheaper.

I think im going to rebuild it myself, I found an auburn posi unit for only $349.00, and the bearing set is only about $80.00. wish me luck, and i would appretiate any suggestions you might have.

Thanks, I found an 8" this morning with 2.79 gears at ecology. I'm going to have it rebuilt with an auburn posi. I decided it would be worth the labor costs to have it done pro. I like the gears better than the 3.00 i have currently with CA's unstable gas prices. Thanks for all your advice.

Your'e welcome. One other site you might find interesting is http://www.precisiongear.com/pgtech.htm It has some good information about the set up patterns and other "tech" stuff.

Well i finally dropped it off at my local drivetrain specialist to have an auburn posi put in with the 2.79 gears. It should get me out the door for about $550.00 I hope to put it in this weekend.
