a welder LOL, you well need to purchase locker system, detriot,auburn make really good products. around $400.00

You could weld the spider gears up but i wouldnt.Do as he said and get yourself a locker.

We weld up the spider gears on the stock cars since they rarely come out of second gear around the dirt track.But i would not do that on a street car.

yea, good luck trying to turn the car if you have the spiders welded together . summit sells auburns for about $400

one why you want to upgrade from a tractionloc[limitedslip] to a posi. both do the same but the posi is little stronger. running spools and lockers on the street suck. if your tractionloc is peg legging it. you can get a rebuild kit for it. to replace the clutches in it. to make it plant 2 tires on the straightaways.

Well the reason I want to ugrade it to a posi is that I am going to build a 65 cobra Kit and I will be using this mustang as the donor car and wanted to have a posi in it

i agree w/ohsoquik, what's the point? have you ever driven posi on the street? no fun...keep the limited slip.

why dont you just get a spool ..dont know why ,unless your track all the time try pushinhg your car 180 deg the a spool an you 'll know what i mean,,,,,if you got a new limited slip,,itr would be just like posi,,..you could still turn,,

Are you saying its no fun because it gets full traction and you cant spin them easy or what ?

I also Have a 55 Chevy I have a posi in that .I drive that on the street all the time and have no problems with it The only time I notice it is when I am pulling out of stop streets or parking lots making a left or a right and I get a little hop or chirpping from the tires skipping on the roadway
