Hi Gary, I think I may be able to help you. I currently have my 1370 apart right now.
You have several options depending what you consider is worth it.
First, I’m assuming that you’ve managed to remove the old screw sucessfully (accidently?). That’s pretty incredible since the end of the screw is flattened to prevent this from happening. If so, then you’ve probably damaged the female threads on the terminal post panel and it will need to be replaced. Try a machine screw of a similar size and see if the threads will mesh. If they do then you’re good.
If the old screw is still in, you’ll need to remove the rear panel (which will require a forked driver or a narrow slotted screwdriver thats been forked using a Dremel or other small rotary tool with a metal grinding/cutting wheel).
Deenergize the unit, remove the throttle knob by pulling it off, remove the rear panel screws with driver as noted above, remove the 5.5 mm nut that attaches the circuit board to the heat shield (this will allow you to better handle the circuit board in order to get your cutters to the screws), cut the bad screw, remove the screw, replace with new machine screw. re-assemble.

If you’re comfortable with soldering, order a new part from MRC, I’m sure that the terminal posts panel is available separate from the circuit board of which it’s soldered to. Doug in the service dept. will send you a new one free if it’s less than one year old. It’s possible that the terminal posts panel and circuit board are shipped from the factory as one intergral part, if so you’ll have to solder on a different part of the board to r&r the power wires.

If you’re not comfortable with soldering, send it back to MRC and Doug will fix it for you.
