NHRA rules state that with slicks or if you are under a certain ET (I forget) that you have to have a driveshaft loop 6" from the front u-joint. Some tracks may not check, but i asked the techs at Brainerd International Raceway last year about it and they said I would need one this year.
I know Summit sells universal kits. I was just wondering if one fit better than another
Where did you get yours from driller?
