Thank you for confirming that. That is something I have been wanting for my own knowledge, but I don’t have access to trucks that age to ever “test fit” for the difference of the cabs and belts.
Some people have said the 3pts work, but never elaborated on whether there was any modifications made.
I’ve seen trucks with the aftermarket belts, but that’s a whole other subject, lol.
Of course, I am not a fan of aftermarket belts at all. Silliest looking things that they are.
