Driveshaft question

[FOR SALE] - CUSTOM DRIVESHAFT 727-8 3/4"

I believe you can't go wrong with Spicer u-joints. But if you feel the need for better ones that are in this driveshaft, their solid versions without grease fittings are on top. That's what I have in my Dart & Aspen, but also use a billet steel u-bolt yoke.
