Looking for some dimensions on adjustable oil relief assembly

[lr172]

Looking for some dimensions on the lycoming adjustable oil relief assembly. If you have one laying around, I would really appreciate a few dimensions. Turns out my engine had the wrong relief cap and I am trying to make a new one.

Most important, I need the ID of the housing base (inside the threaded area) and the depth of that bore up to the step where the ID shrinks. Also could use the depth from the sealing base(where the crush washer goes to the very bottom of the unit, just below the threads.

Really appreciate any assistance you can provide.

Thanks,

Larry
