so im looking into buying a new to me crewcab truck its a 89 2wheel 3500 for 950 , its got the 454 and an auto trans , I have some questions about the truck before i buy it though , if i wanted to make this truck a standard trans what all would i have to do? also how hard would it be to make it 4x4 , I am very mechanically inclined and welding and fab work isnt a problem for me , when i was younger i built 4 4x4 tube chassis trucks for me an my buddys as a graduation project
