This is what I've come up with so far. I've temporarily "robbed" the turntable out of my Crosley 10" combo, which appears for all intents and purposes, to have never been used. Not ideal, but I might be able to make it look nice

. I intend to make a board out of the same wood, and bolt it down over the existing cutout, using the existing holes to secure it.
Problem is that there are two belts on the turntable for the changer mechanism that I need to get. They are roughly 2 1/4" circumference, and 1/4" wide. About the size of a #61 rubber band.
Anyone know where I can get them? I hate to just use stupid rubber bands on this thing. There are no markings on the turntable to identify the manufacturer.
