I got a new Weaver 57' 2 rail reefer for a great price on eBay. It came with sound but the seller, I think, did not know that. I have two questions. The first is how does one open the reefer to gain access to the electronics inside. Something has broken loose and is rattling around inside. I run 3 rail so I want to convert from 2 rail to 3 rail. This is easy enough, but this leads me to my second question. Where can I get the coupler assembly for 3 rail that has the pick up roller. I have the MTH Weaver trucks, and if I run without sound they will be fine, but if I want sound I will need the coupler assembly with the pickup roller.
Thanks,
Ed
