Random DS Question

[ganma_ca]

So i have been wondering what the limits of our stock 2 piece drive shafts are?HP/TQ wise, or when to replace it with a single piece shaft instead? I know there are a few die hards out there that say to stick with the stocker, but I'm already beginning to wonder after 16 years on this one how much longer will it last?(though could be a reman because i bought it from a friend and it looks pretty new). My old one's center section was fragged!
