Hello from Massachusetts

[Classicdes]

Thanks for the ad! Recently bought a 1951 chevy p/u that I have a few questions on? The sheetmetal is rust free but the truck was stripped and mounted on a 1979 k-5 blazer chassis. So basically I have rolling sheetmetal from the cab forward...bed/fenders wont fit because shorter wheel base.
#1) its a long bed. does this make it a 3600
#2) what sits between the fenders and hood, cowl and hood
#3) I don't have vent windows but it seems they should be there
#4) I see some have chrome reveals around glass, some don't
Any help would be greatly appreciated. Thank you
Jim
