awesome timing on how to install door glass on international trucks... I have a 1977 IH loadstar 1800 with no flat glass... all gone / busted out... except the windsheild in process of stripping out the cab for rust repair work, cab floor replacement is easy.. the hard part is fabricating the fresh air vents under the dash on both sides (rusted out badly, due to rat / mouse nests) ..and figuring how to repurpose a 2004 International Workstar heater / ac box to replace the rusted out heater box.. Soo much fun saving old binders from the scrapper's torch
