Getting some cab parts...(Mk. III content)

[camsna]

Hello all. I recently got myself a Mk. III combo. I pulled the chassis to check it out and blow it out and change the tubes. When I did - the screws almost melted. They stripped out instantly. One of the heads even popped off! One came out with no problems. The other 2 had to be drilled out.

Anyone know details about the screws, washers, and 'cups' (sorry. dunno what they're really called) that they all screw into? I'd like to replace all of them.

THANKS!

Thanks! 8-32. Can do!

Any idea about the 'cups' or whatever they're called ?

Well. One is all scratched up. I tried to dremel a notch in the stripped screw head and gored the sides a little. But - if Mesa's got them, I'll have to hit them up!
