Did you mean Model 37-640? Can't seem to find that one on Nostalgia or Breitman. Most of the time the micas are inside the can, and sometimes even another couple of components can be found hiding there. If it's just the two screws that need to be removed to get inside, then it's not that bad . Don't even bother measuring them if you take the can apart, just replace them, use fresh stock, they go bad whether you use them or not. You need not ask how I learned this. I always replace any resistors I find inside, and use heat shrink tubing or replacement wire if the leads are shabby.
