I drilled and tapped for a relocated grease fitting. Used a cobalt drill because the axle is very hard. I ended up pulling the kingpin in order to drill clean through because it wouldn’t take grease.
The relocating was necessary on mine as I wouldn’t have been able to connect the grease gun.

Is that an issue still? I ordered the 5x5.5 kit, and I have a spare set of spindles I plan to use for some bench mock ups before installing on the truck.

I didn't have to relocate them on mine.

Flex lines

I have had the truck out a dozen times this year. I think I will lengthen front flex brake lines to create a bit more slack.

I've read that also, where some people might have to relocate the grease zerk and/or install a 90 degree zerk. I didn't have any issue on my 49. I've been involved in a couple of other conversions and we didn't have to change anything on them either.

It doesn't surprise me, these trucks were made in several different factories and I'm sure got parts from several different suppliers so there is bound to be differences.
