Yep, that was me. I thought the ones I had but when I checked the caster on the right, it was out. I'll clean up the pair I have and spray it with black rattle can - or whatever color you want. I'll also check the dimensions before I send them but they are perfect to look at them. There are bushings in them but they a probably the originals so you'd probably want new ones. When I get them cleaned up, I'll pm pictures to you.
Thanks!!
