If you happen to have access to both old and new metal go buy a guage.
I have seen them at the metal shop in town. I dont think it wouldbe tht expensive. It has litte notches you slide each piece of metal into to check its size.
Seems simple enough.


Don't you know who I think I am?
I've been thinkin' about freaking out. If I could just find the time.
