Check Fixture Design For Sheet Metal Part

Looking for some input.

We have a flat sheet metal part with some window features that we then weld threaded studs onto. The location of the studs are dimensioned X-Y from the same datum window. Unfortunately it is not dimensioned geometrically and the customer isn't interested in doing so.

Our engineers have designed some whole part go/no go gages ( stud location-datum window only) but they have never worked. Our 'solution' has been to heavily sample on a cmm, not where we want to be.

When something like this is dimensioned straight up instead of using GD&T I am wondering if we are going the wrong route. Would like to know if anyone has encountered like problems and what kind of solutions they've come up with.

Thanks,

Has someone experienced a similar situation? Can you share?
Any suggestions?

Thank you.
