jb505, it is not too difficult a task if the current cord has a non-molded plug end. The plug will disassemble fairly easy leaving the hot, neutral and ground wires pre-stripped and ready to go back into the new plug. If it’s a molded plug then you have a bit more prep work to do after cutting off the end, but still not high on the diy difficulty scale. Several good YouTube videos to watch to get you acclimated to the job. It looks like you are in the Sacramento area? I’m sure someone from here that is close by and proficient would offer to assist should you want to go that route. Heck, if you were near Philly I would gladly do it for free.
Wishing you success on your project
