Yep , 97 . Keep an eye on the brake codes when ordering parts . JD8 and JB8 makes a difference . Mine is a 91 Suburban which is technically a V 2500 squarebody . I also have an 86 CC dually and between the 2 it makes a difference when ordering brake parts .
As am I . Maybe someone else will correct this . Really the 6.5 is a 396 or 7 so ...
Could also check the vin code . Should be an F for the diesel . Count across 8 spaces from the start . Should start with 1G1 , 2G1 , 3G1 or something like that . Sorry just reread your specs , should be the diesel .

GT5 is the rear axle code .
L65 is for the 350 gas engine .

Ever think about running another coolant system for just the heater ? Heat exchanger for the heat source , engine coolant in one side and heater on the other side . Extra heater hose and water pump like the cooler for your turbo .
