New owner of a vendo 81d

I just received this machine, which is in really great shape.  It does have two problems - nickels drop right through to the change return (not revealed in the ebay ad) and two of the long rods that let you adjust the opening (3 settings) have been replaced by long screws with a nut in the back - which will not come off!  Inside and out are otherwise perfect.  I ordered a chrome crank too.
