Im want to try to make a set of CNC trucks that are compatible with randal baseplates and would like to know some exact messurements. (All I've got is a metric ruler and figuring out the pivotlength is a pain. I would say my messurements are at best +/- 1mm and since I can get these CNCd Id like to make it as precise as possible)

The messurements I would like to know:

Pivot length (Middle of the KP hole to end of pivot)
Pivot diameter
Bushing diameter and height

Thanks for your help.

PS I have used the search, read dozens of pages and couldnt find it. ("randal messurements" gives quite a lot of search results...)
