This probably is a silly question but here goes.
What is a good driveshaft?

ops: What I mean is...what do I ask for / look for when shopping for a drive shaft? I have never used anything but a stock drive shaft and U-joints,and have never had a problem.. but I've never had a car that left as hard as this one does either. What is the difference in the universal joints ? Are they solid or what? Just made from better material? The car weighs just over 3000 lbs and the 60 ft times are low 1.30's with a best of 1.32.
540/ glide with brake.
So I guess the actual question I am asking is..If I go to have a drive shaft made for this car..what do I ask for?
Thanks in advance for helping out a green horn.
