Hi guys, new to the forum and new to large scale railroading. I have recently acquired a few 4-6-0 "Ten Wheelers" (2 gen 2 and 1 gen 3) with a small assortment of rolling stock, all from the "BIG HAULER" line. I'm looking at converting the couplers on all components over to Kadee's. The reason for this is to have a functioning front coupler on the locomotives for double heading and pulling cars in reverse, and to have uniformity on all the rolling stock and locomotives. From my research on some other threads I believe I need the Kadee 791 for the locomotives, and the 831 for the rolling stock with truck-mounted couplers.

My hiccup on this conversion project is a bobber caboose I have has body-mounted couplers. Does anyone have a recommendation on what Kadee couplers to use to convert this caboose?
