1974 dodge w200 360 727 trans
 

MSD ignition box blaster 2 coil MSD and wires to match new spark plugs I set the truck at tdc and backed the harmonic balancer to zero and started my firing order from there being a novice I just looked up the firing order ( wrong one) online and it was revealed to me that the firing order was on the intake manifold do I have to go through the process of refinding top dead center or can I just switch my firing order to the correct firing order

AS long as you remember what tower number one was on the cap when you installed the distributor. Then you can go from there...
If you don't remember, then you have to start from the beginning...

I know there are about 2000 production power wagons in this Omaha Orange. I’m wanting to keep it as original as possible but adding disc brakes ect. But I’m wondering if it would be sacreligous to cut off the cab drip rails? I just want to be a good steward of the original truck.

You realize that in cutting off the drip rails you remove the bond and bonding area of the roof. This might leave a gap between the skin and the roof structure which will need to be repaired and welded together.either way there’s a bit of welding to do removing drip rails.
