    My goal is to turn my stock rear end of my 72 Comet into a positive traction. My buddy said it would be cheaper switch it to a 9 inch rear positive traction. My just trying to find the best and cheapest way do make it a posi overall.

    I put 3:80's and a new Traction Lock in my 8" for about $550.00....Lighter than the 9" too

    Did you have the stock 8 inch rear?

    Drives great but if it's for an everyday driver without an overdrive, the 3:80's may be a little steep....Might be better with something closer to 3:25-3:50

    IIRC, there can be a weight penalty of about 40 lbs, using a 9 inch vs an 8 inch. An 8 inch will stand up to a lot under a light car like ours if built right.

    You should look into this

    http://www.richmondgear.com/powertrax/lockright.html

    or this

    http://www.richmondgear.com/powertrax/noslip.html

    you can do either one yourself with limited knowledge. I had NEVER seen the inside of a rearend before installing mine and I just followed the instructions that came with it and a couple added instructions from the internet and mine has been in for 2 years now and I have not been easy on it to say the least.

    BTW either of these install into a stock 8 inch rear.
