It would really depend on your application. My jeep for example has 60's, a tummy tuck skid plate, motor mount lift, etc... so finding one that is specific to my application would be difficult. Now if you were running stock axles and mostly stock things and just put a 4" lift on then you probably are fine buying one from quadratec since that is generic enough they already have figured out the dimensions and such.
Edit: Now that ive looked at the link its actually just them reselling tom woods drive lines. With any driveline you can actually measure for it on your own at your home, then provide that info to a tom woods or other shops and they can make it for you that way. With how close i currently live to the driveline shops it just makes me feel better knowing they took the measurments and its going to be a perfect fit.
It was a Jeep thing, but all that stuff broke

Tom Woods is located up in Ogden. They built my driveshaft to and i just provided them the measurements. My Dad was working up there at the time so he just picked it up at their shop. So Far i have no complaints on their work.
