K4003 incorrect mica insulator supplied

An incorrect mica insulator was supplied. The supplied washer measured 25 by 20 mm and had one 3 mm hole 7 mm down from the 22 mm edge.

I was able to modify it by punching cut outs on each edge to accommodate the fixing bolts.

Also I thought the connector pins were a too easy fit in the pcb holes.

When one turned the board over to solder them they fell out.
