I'm looking to identify the brand of the hydraulic controls that Dynamics used in 2010 on each side of the tow truck to run the bed functions. They are 6 lever 2-way hydraulic valves in a single body. I have one lever that is physically broken inside (last one to the rear, drivers' side), which extends & retracts the under lift. I'd like to find the repair parts to fix this valve body. For those who don't know dynamic is very difficult to work with as a company. they want you to go through their authorized repair people. None are local to me. So, no chance of taking the truck to them for help. I just need parts help anyway. If I can get a brand name, I can find the parts online myself. I know the truck is old, but only 156000 miles on it so far. Any help will be greatly appreciated!
