Thanks Pete and everyone, really fantastic input. Using the new bolt info, it's refined a little more: http://web.aanet.com.au/~malikoff/pdp11/DEC_H960_stabiliser_foot_left_A-H952-BA_revision_3_dimensioned.jpg I can't find anything suitable on MMC (https://www.mcmaster.com/#countersunk-head-machine-screws/=1b0p4yz ) so Chuck's probably right, machine them up. Maybe start from a long 5/16" shank hex-head bolt and put the countersink and 1/4-20 thread on. Thanks for the drawing for the kickplate. I'm assuming the plate goes on after the feet have been placed on the rack, and the #10 screws hold it all together. I'm guessing the kickplate is 16 guage sheetmetal..? Steve.
