Have a 46 1/2 ton pulled apart about 15 years ago doesn't need much work but I need to know what is the best manual or manuals to buy to get this thing back together again. The Body is off and the drive train is out I will be replacing the 216 with a 54 235 the guy I bought it from had replaced the closed driveshaft with an open one. The truck is in pieces all in boxes but so you guys got any idea where to start. Thanks
