The side windows are 31 in at the longest point and 12 in at the tallest. They are pretty close to 35 -36 ford 3 window but the upper right hand corner is too square. the vent windows and front would work perfectly in the 3 window though. The back is the the same as my 35-36 3 window same shape and everything but and an inch and a half too wide each side. Thanks for the help Kevin
with vent window,If they are Ford,would be later than 1939.40 was first year for vents on side windows
