I can't seem to find the right size. The ones shown in the package are similar, but I doubt they will hold up. Mine are nearly twice as wide as the ones in the package.
Thank you,
Anthony

Hello, Anthony. Take a look at our 87-190. The housing seems to match. The wheels are nylon with stainless steel axles, with a 1/2" diameter and the thickness of 1/4". See what you think.
