mark IV chassis screw size?

[JimAnsell]

anyone know what size screws are used for the mark IV chassis in a head shell? i have the newer head cab with the fender style chassis straps, but it didn't come with screws from the seller.
anyone know what size i can use?

You're probably going to have to get them from Mesa. Even if you knew the thread size (it's probably number 10, if I had to guess), you'll not find anything that small in sufficient lengths at a Home Depot or Ace Hardware.

And they're bigger than Fender screws, so you can't get them from the myriad of Fender parts suppliers.

The newer amps use a 10-24, the older amps with SUS-4 use an 8-32.

You won't find the length you need anywhere but Mesa, or at least, I haven't yet but I keep looking just incase.
