Install posi into exisiting stock 10 bolt.... or.....   Change complete rear to 12 bolt 

Depends on how fast the car will be running at drags   Stock 10 bolt will be strong enough into low 13.s

 It depends on what your looking for ... I went from 3.90 posi to a 3.55 posi because driving down the highway I was reving over 4700 rpm around 70 mph or so... and the redline on my Ram Air III is 5200 rpm..  I lost alot of playing area.. but its a bit nicer on the highway now.. I almost went to a 3.23 a couple years ago.. But glad I did not..

 No, I am still using the M40 - Turbo 400 ..   I have been told if I switched to a 700R4 that it would be the best of both worlds  with the 3.55's ..
