Find a slim fit 5/8 plug socket. I got one from sears that was thinner than my others. I read Home Depot has a Husky brand plug socket set that will fit. I'd take your socket that doesn't along for comparison. Otherwise if you can't find one, could always try a 3/8 drive, 5/8 deep well socket and a light touch. Goodluck
