If your rough on things, I highly suggest not getting a joint with a grease fitting on it. I know that sounds wrong, but the joints that can be greased have hollow passages through them and are prone to breaking under hard impact stress.
At the time I was unable to locate a conversion joint that was non-greaseable. I wasn’t about to buy another greasable joint and have it explode, so I had my drive shaft modified and got a bigger yoke on the rear end as well. The 1410 joint has been great for several years and 40-50k HARD miles now.
