So i see all these 2000 2002  1500 rams for great prices. If i
bought rhe 02 and wanted to replace parts on my 2014 um
looking to replace hood doors windshield bumpers? If i can
take a 4.7 truck apart to make my cummins come back to
life.  Second part if not a d i decide to do a whole body
convirsion what would make it worth the most.  I was
thinking a 4 door long bed international body or a pannel
truck old ford old dodge im so undecided if cheap 02 parts
wont bring it back what will make the value the most for a
body swap keeping in mind i have 2wd cummins.. Idk rat

profitable.
