sorry i seen this setup mounted to a engine on ebay and i emailed the owner and asked for some pictures of the slave cylinder and he sent me some, but come to find out i had a very old hostees van at my dads from the late 70's early 80's that had some huge 4 cylinder diesel in it (i was told it is a english ford diesel), but it had a t18 mounted to it with a hydro clutch and it is the same one you see in the picture, i will try to clean it up and get some numbers, i know the name on it is a long 2 part name and the last name is "lockheed"
