Removing side-view mirror
Mount plate is an original part #: 5946478 w/correct philips screws.
Note: base should use a black sealing pad (not tan).
Back of mirror should be stamped "GUIDE Y-50 MADE IN U.S.A."
No stampings on the back
As mentioned in a prior post, there should be no date code or manufacturer stampings.
This DMI stamping/date code is typical of C2 mirror glass.
Pass.-side door glass. Code: NT = January, 1957
Driver-side door glass. Code: JT = May, 1957
Pass.-side acrylic Plexiglas hardtop window. Looks like "5-7" (May '57)
Driver-side acrylic Plexiglas hardtop window. Looks like "6-7" (June '57)
Hardtop acrylic plastic (Plexiglas) rear window.
Can't make out date code 1-something. Most likely a "1-7" for Jan. 57
