Notice you got no answers so here goes, i do not have the book so cannot refer to the pages you mention.
I would put the mast foot track pin in to start with and maybe leave out the pivot pin,do all your setting and see if the pivot pin goes into the tabernacle and mast.
If you have jib tension lever or pulley box put the heel to the mast track pin always as that will be where you will want to be when sailing and setting up.
6mm pin gives you more movement around the pivot pin,ie chocks and mast bend. you dont want the pin binding when sailing.
Tabernacle whole size 16mm max. make new plates with 16mm holes in
and screw to side of king post,follow rules.
Shims are often used when a new mast is fitted to an older boat,watch the height from the sheer for the pivot holes then lift the mast track to the pivot hole.
Mast side and front spacers to fit the gap but still the mast must be able to move ?
Washers,I dont bother but tape the rings up so as to not rip the spi.
Measurements, Have the pin in.
Hope that helps, Well a bit anyway!!!
