i'm about to change the plugs in my truck. with all the different types of plugs out there does anyone know which ones are best for these old trucks?

 

Autolite 45 still work very good. IMHO

I prefer NGK plugs.....unless it's my old 74 Beetle...then it's only Bosch Copper...

Steer clear of "splitfire plugs" (which don't work well) and "platinum" plugs, as the electrode is usually the size of a speck and oil or debris and foul them quite easily...and often.

I just put some NGK's in my 75 today. Always had pretty good luck with them.
