On my 88 951 my clutch pedal has recently started sticking on the floor. After reading a lot about it I surely thought it was slave/master replacement time. But after driving yesterday briefly I noticed it returned with an audible THUNK. Goes in/out of gear fine and only sticks infrequently. When I got home I crawled under the dash to once again check for interior fluid leaks at the cylinder and found my clutch power spring isn't held onto the sheetmetal by any cotter pin or clip. I've read a few posts about it not being needed but after depressing the clutch whilst under there it absolutely falls out of the hole in the sheet metal, gets bound behind and causes the clutch to be stuck monetarily on the floor. I cannot however find a photo or part # for the clip that would hold this in place. See diagram below.
Can anyone take a photo of their power spring/helper and show me how it's secured to the sheetmetal?
