Whenever i repaint a 4018 boxcar it seems that there is always at least one door rail with broken tabs. I managed to buy a bunch of these. Since I got more than I'll ever use I have 6 pairs for sale at $5.00/ pair plus postage. These are the door rails that are about 4 3/4 inches long and have 3 tabs. I used to buy these from PortLine hobby but he's out of stock. I think my price is comparable to what he used to charge.
