MY GRANDFATHER IS BUYING A 1993 DODGE POWER RAM 4X4 EXT CAB,CTD, 94000 MILES ON IT, POWER EVERYTHING AND A/C FOR $8000. HOW SIMILAR ARE THE FIRST GENERATION RAMS TO MY 97 CTD? IS THERE ANYTHING THAT YOU CAN TELL ME THAT WE NEED TO CHECK ON IT? I'M A NOOBIE TO THE DIESEL CROWD, (BOUGHT MY FIRST CTD ABOUT ONE YEAR AGO)I KNOW A LITTLE ABOUT DIESEL ENGINES, BUT ANY HELP WOULD BE GREATLY APPRECIATED. THIS IS MY FIRST POST, BY THE WAY. THANKS FOR ALL YOUR HELP!!!!
