rear view mirror '67 F85 that i had, had a slightly different mirror mount/visor support. the visor "tips" pushed down to lock in. my 67 supreme pushes up to lock in the tips, and i would like to change to the other style. anyone have a part number? ive looked at ebay, year one, opg, all i find are the supreme style ones.
TIA
