Looking to find the correct size of run channel for side window
on 64 fury

When I did my '63 Savoy many years ago, I came up with a measurement, which I don't recall now.
When I went to order the run weatherstripping from Restoationspecialties.com, the guy there corrected me, shipped the correct size, and it was perfect.
I'm still impressed that he knew that. Used them again on my '64.
