Anyone have any experience with them. Good bad?
I'm looking at buying a MMC aluminum DS from them.

I bought from them and they're great. I don't remember the person's name but he asked me about my intended use and didn't oversell me.

I bought a Heavy Duty driveshaft and it fit perfectly and runs smoothly. They were very helpful and walked me through my car setup and made a recommendation - didn't oversell.
Good Luck

Have a Denny's nitrous-rated model in my 69' with the billet yokes,etc. She's expensive, but what a nice piece. Very well made product.

I've also got the HD driveshaft. Fit and operation are A1. They're great to work with. They're website has a great diagram showing all the needed dimensions.

I bought a denny's steel driveshaft years ago and am thoroughly satisfied. No more vibration problems these come without any balance weights because they are perfect; doesn't need em. Denny's Rocks. graemlins/thumbsup.gif
