Hi all I managed to fix the ATU roller coaster with a piece if 3mm fiberglass sheet which I cut and shaped to correct size, only to damage the output switch shaft when tightening up the SO239 output sockets which had loosened.

Has anyone in there extensive parts draw or knows where I can acquire a 80mm min length of insulating drive shaft for the ATU output change switch.

It appears to be Bakelite or something similar was 80mm long before disintegrating 1/4 inch in diameter and 3/16 across the flats but could be 6.2mm diameter and 5mm across flats which is approx. the same.

See photo of remnants.
