I have a 1953 3600 that I will be updating and converting to 4WD. This will be my 3rd 2WD to 4WD conversion.....but 1st conversion on an advance design truck. I will not be using NAPCO parts. I am considering installing 2" wide 3800 front springs in my 3600 to handle the additional weight of the drivetrain and to better fit the 4WD axle. Is it possible to install the wider and longer 3800 springs on a 3600? Are the 2" shackles and spring hangers available? Are the rear hangers in a different location to accommodate the longer 3800 spring. Or alternately, I could have 2" wide springs made by St. Louis Spring Company to match the length of the 3600 springs. Thanks for the help.
