Default Drive shaft diameter?

I have to have a complete new shaft made for the 28 Dodge. OEM shafts can be any where from 2" to 5" dia. What do all of you recomend?

Don't give up, it's far too much fun once you can drive it.

Depending on the horse power and length. The smaller the diameter the thicker the wall too.
I never use anything over 3"

The last two have been shorties. They are 3". Gonna order one for the roadster today and I'm sure they will make a 3" again. Mine is 23" long also.

I get 'em from Driveline Specialist of Texas. About the same price as local but I trust them to not screw up or take advantage of me.

I prefer a 3" as well, solves a lot of clearance problems too. That's what I'm using on my current build with a BB Nailhead. Had the same set up in my truck & never a problem... other than keeping tires on it!
