1940H manifold pain

Simple job made difficult by screwed up parts. Ordered a replacement manifold for my H. When it showed up I realized I needed all six of the small thick washers for the studs, so I ordered those and cleaned everything up and waited. Parts show up and I get started but the hole in the washers is too small, OK, ream them out to fit (hour wasted). Put the manifold on to find that the relief in 2 of the runners was not nearly enough. In fact the high points on the nuts actually touch the manifold when put on. How could they do this? Am I the first one to buy this thing? Everything else about it looks perfect but how could you end up with such a crappy flaw in the design? I'm not sure I got those 2 tight enough with an open end (couldn't get the wrench all the way on the nut). Last resort would be to pull it back off and use a die grinder on it (don't want to do that). Maybe I'll try to make or modify a wrench to better fit the nuts. Just venting. Can't be the only one this has happened to.
 
I have run into issues similar on other items. Bought a new pedal shaft for a SMTA and the key ways were clocked wrong. So tried another with same result. Vendor would not accept the fact they were wrong. Ended up having new key ways cut so it would work.

I would be hesitant to grind on it unless you know that it is thick enough. Maybe remove the studs and use an allen or 12pt type headed capscrew instead. Just a thought.

Not only after market parts. When I worked at the Deere dealer, I ordered a short shaft in the
power steering of a two cyl tractor. After six different shafts and trying to explain to the parts
dept and service mgr trying to explain to Deere parts people, gave up, modified the shaft and
installed a half moon key that sat straight up and down , not leaning to one side so it would
properly fit groove key had to slide back and forth in.
