I'm having a heck of a time trying to find replacement parts for my Kiekhaefer Riser, part numbers 50186 & 50187. I'm specifically looking for the spacers that go between the manifold and riser. It's 3/4" on one side tapered to about 3/8" on the other.
The damn things are so rusted and pitted that I can't get a gasket to seal up in there and she keeps hydo-locking.
I've been pulling my hair out over this for the past couple months!
Any suggestions??

Lucky

cant you just replace them with more current updated manifolds?

I could but I'm not looking to spend a bunch of $$$. The manifolds are ok it's the risers that are out dated, but they still look great.
I was thinking about taking the spacers to a machine shop to see if they can fix them up.
