Thanks for all your advice guys, I appreciate it. I too like to be able to split the doors. I enjoy working on the old Dover/TKE, Montgomery, ESCO cars. I am concerned that the larger companies will begin to obsolete parts for some of the older style door equipment. I am having a hard time getting TKE Vertical Express clutches and some MAC equipment from Spares. Like for like swaps on mods make the jobs cheaper and quicker for the customers.
