VT-40 Top-Loader chassis and back panel mounting screws..

[Steelyman]

I bought a VT-40 that came without any screws to mount the chassis and back panel. Anyone know the kind of screws needed to mount a VT-40 Top-Loader chassis in the cabinet and the 12 back panel screws? Are they all the same? Are they machine screws like 8-32 x 1.25" or sheet metal screws with a point like a wood screw? I realize that original hardware might be difficult to get. These look somewhat like most of the Ampeg screw/washer I've seen...

Any other alternatives?
