[rickyracer1962]

Hey guys i'm so close to wrapping up this 36 restoration, trying to fit the top irons now. I need the dimension from center of windshield post stud to center of windshield post stud, basically where the top sits over. Can anyone give me that measurement so i can see if this one is in the ballpark. Im getting about 46-3/8" but the wood header fits pretty tight, hard to get back on once you take it off. Need to figure out whats going on
