McIntosh MI-75 Front Panel Question

[bhutchin]

I have a pair of McIntosh MI--75 amps that I am restoring and they are both missing the front panels.
I have had a couple new blank rack panels fabricated with the proper opening for the controls, but I have no information on what type of fasteners were used to secure the original panels to the amp chassis.
Can someone provide a photo showing the detail of the original fastener close up? It appears to space the panel about 1/4" from the amp chassis, but I am not sure if it is a threaded unit or something like a camlock fastener, or just a spacer between the panel and the chassis with a screw that goes into the rack rail just adjacent to the screw that holds the chassis to the rack rail.
I have totally recapped both units and replaced the original rectifiers. They sound amazing.

I restored two of them this year. If I remember right there is a 1/4" bushing spotted welded to the front panel which is a sheet metal with 1/4" flange at the top and bottom. The customer had the panels and the sub panels powder coated, then had a graphic firm relabel them. They came out really nice! He also purchased these mini rack mounts.

I've seen those photos before. What a great job!
Thanks for the reply!
I am in the Southern California area and am presently looking around for someone to do the graphics, but wanted to get the hardware complete first.
