Here are some parts I got from Scale Art, hoist and pump, relay 2 cable locking rear ends and 2 SMX sound modulars. The rears are for the tractor for the dump trailer and hoist,pump and relay are for the tri axle Mack I am going to do. The sound modulars are for the equipment. Thought you might be iterated to see the hoist and rears and pump. I would be very happy to answer ay question about these parts if you have any. Click on picture and it will take you photo bucket and you can click away. Ed
