some hint's from frozen Turner Valley, Alberta
can't get to my truck to meassure. It's outside in a tent and 3 feet of snow around and -25 degree.
loosen all bolts. check the suppert arms which come from the fire wall to the front end of the inner fenders. meassure if the adjustment nuts are the same distance. there is a starting point.
also ypu have to check the cab meassurements to the fram and also the radiator support. ( I made the mistake and got sloppy doing this adjustment)
If those two are correct spread the two support arms till you have your 30 5/8" than start adjusting ( cursing) twisting ( cursing) pulling ( cursing) pushing ( cursing) you get the drift.
You have another 6 month till sommer arrives in your neck of the woods.
If you go to the tech info on this side I think there is a good write up whow to adjust a hood.
