Ron, can't help with the part you need, but I can strongly endorse the customer service you can expect if you contact Precision Scale Co. as Bob suggests.
Just today I had my first contact with them when inquiring about a mail hook bag for an RPO car I'm making. The part was named, but w/o p/n, in their catalog index, but was not on the catalog page specified. The helpful lady, Teresa, took my name and phone no. for a call back after she confirmed the part I needed while she researched the part.
She called me back in less than 10 minutes with the part in hand to answer the few questions I had. She invoiced me via PayPal; I paid; and, my mail bag hooks are on the way to me.
Hope you have a similarly satisfactory experience.
