WOW thats some nice neat work and alot of money ,I would not hesitate to get a new one made at a race shop just for the safety of my nice ride and peace of mind.If it did go ,not counting bodily harm ,it would wipe out close to a thousand dolloars in parts ,2 muffs and that polished stainless hard line and those anodized an fittings,not to mention all the other stuff it could grab along the way.On a project like that ,toss that old questionable driveshaft with the dent in the can! along with the yokes and u-joints.With a investment like that I would go custom carbon fiber,not only add value and look trick,but way way safer if it does pop and less likely to take the rest with it!!
