I have MkIV 7622. When I took my initial inventory, I came up short the spring in the e-brake handle set. I called a tech and was told that my style doesn't have a spring. Now as I prepare to assemble it, all three sets of instructions I received with the kit shows a spring. I can't see how the release button can function without a spring to set it out. Am I just getting feeble or are there two different assemblies. Thanks Nick Chelenza, Lawton, OK
