Kadee Conversions The Zelatory One company that makes some nice conversions is "The Zelatory" His web site appears to be gone, but it's on Z Scale Monster's site: http://www.zscalemonster.com/zelatory/ The products include: a small "spine" that fits a Marklin long caboose and body mounts Kadee trucks and couplers. A kit to body mount kadee trucks and couplers to the Marklin Mikado/Pacific tender A kit to mount kadee trucks and couplers to the old time Marklin coaches, as in sets 81438 and 87910, does 4 coaches A kit to mount kadee trucks and couplers to the Marklin "short" tender as in the 81438 A super detail kit for the long caboose, though currently listed as unavailable, apparently he needs more interest to start production. I bought the tender kit and the caboose kit, great stuff, makes the job easier. Note that couplers and trucks are NOT included.
