So tomorrow I will hopefully be getting a Cummins it's a 1997 Dodge Ram 2500 12v single cab long box with the 5speed tranny and it's the work stock manual everything and rubber floors how hard would it be to convert the locks and windows to automatic and also are there any things I should look for this is my first time buying a diesel

 

You may find Power lock conversion can be a PIA. Maybe easier to buy truck with it. Or go with manual.
