Check with Little Machine Shop for the gibs, I have a LMS 3990, not expensive, but you have to put in
your own holes or indentations.. I used a 4mm end mill in a v-block, lucky to have a second
mill. My Z axis gib was also slipping, now the indentations are square bottomed.

I use way oil and regular zerk grease fittings, but the gun has to an 'Oil Gun', I put in
extra 6mm holes for the fittings, and also Oil grooves.
