The heck of it is, is that it's a silly stainless steel flange for the exhaust header. 4 port holes, 5 bolt holes, laser cut out of 8 mm stainless plate.
Aaron Thompson was my shop teacher in high school. If I had handed in a project that was this far off, he'd have had me do it again.
I read about this in the Milwaukee Sentinel about 30 years ago. Before Harley-Davidson was sold by AMF, they literally had to scrap tons - and I mean TONS - of improperly machined transmission casings sitting on their warehouse shelves. They worked on the production line, because the assemblers did "work-arounds" in order to make them fit. But if you needed a replacement part for your existing motorcycle, it had to be virtually remachined in order to fit.
The aluminum intake flange I bought from the same manufacturer - which it looks like we won't use - is just as bad.
Now this is from a manufacturer who makes entire manifolds for the K series.
As I mentioned earlier, I had similar QC issues with an Edlebrock Perform manifold - but at least the bolt holes all lined up.
Though I'm past the thirty-day return window, and could probably pitch-a-bitch and get a credit, but it's simply not worth the time or the cost of shipping it back to England.
I'll probably take the intake manifold flange, screw a couple of L-brackets on it, and install it in the kitchen to be used as a hanging spoon holder.
