I auctioned mine off when we was trying to raise money around x-mas for Mary. I couldn't get it to fit correctly with my exhaust in the way. I need one just in case but have not looked very hard for one that will maybe fit. I took a friend of mine for a spin and he asked did I have one and I said no.... he said you need to get one! LOL!
You`ve got to make some serious hp and hook up really good to spin the tire on the rim but if you think you might be there, mark the rim and tire and see if the marks move.
I had a 68 Charger with weld wheels and a 383 , 4.10 gears, auto, and 3000 stall. I screwed those wheels to the tires just to make sure. I bought some drag radials for that car.... man that car would hook and fly!
