The holes in the rubber shock mounts are for a size 8-32 screw. The Mark chassis are all 8-32 as well, I thought. I know you won't be able to get a larger screw thru that shock mount and I'm not certain that they make that size (1") mount with a larger size hole in the center.
If you could find a way to thread an 8-32 UP..from the INSIDE...thru the mounts and secure it with a nut on the outside.
Hmmmm. You can do this.
Use 8-32 roundhead machine screws,put a star washer (lockwasher) on the screw and then from inside the chassis push it up thru the hole in the chassis. Use a Tinnerman nut (REAL THIN stamped metal nut) that will fit the screw and tighten it down against the other side of the sheet metal chassis holding the screw firmly in the place. Do this on all 4 corners. You should now have 4 8-32 screws all sticking up from the edges of the chassis.
Now have someone push the amp up into place,threading all 4 thru the shock mounts. Use a nut with a lockwasher to secure.
Piece of cake!
