Driveshaft rebuild - u joint problem

I'm rebuilding my driveshafts. I purchased replacement u joints from a main bronco parts supplier. The u joints are all the same, a replacement for spicer 5-153x.

My problem is that the u joint grease fitting or zerk on the cardan end of the driveshaft will contact the driveshaft for part of its range of movement. If i remove the fitting and plug it, the threaded boss on the u joint housing will still contact the driveshaft.

Will this be an issue for me? My truck will primarily be pavement driven with some mild gravel mixed in.

I've noticed that the old u joints in this driveshaft position were non greaseable.

Do I need to find a different u joint, either non-greasable or with the zerk in the end of a cap such as a Dana Spicer 5-1310-1X Driveshaft U Joint 1310 Grease Zerk in Cap https://www.drivetrainamerica.com/5-1310-1x-dana-spicer-driveshaft-u-joint-1310-grease-zerk-in-cap/?

I would use a carbide bit and clearance it so it does not hit. The other option is a pin type grease fitting that sticks out less.

You could always pull the joint and flip it!
But since that is a PIA.... get a needle type fitting

Reality says it will only hit once. After that option I'd go with the needle zerk.

The same problem exists if its flipped. And a needle type fitting will also contact the driveshaft.

what brand joints are those? I just used spicer joints on a double cardon joint and had no issues with the fitting making contact

If my memory is correct, they make an angled zerk fitting that will clear. I am old and may be misremembering this, however.

Bitten by the offshore junk again. You'd think I'd learn. Why would the vendors sell these kits that don't fit properly? The u joints supplied only work on the two outer positions, but won't work in the interior cardon position.

I've ordered some Spicer 5-1310-1x u joints that won't have a clearance issue.
