So I've been searching a bit to see what year GMC switched to front discs on the trucks. It seems to be 1970, but I'm not certain. Can anyone confirm this? I drive hilly country; discs are nice.

Thanks!
George

My understanding is that in '71 disks became optional and in '72 became standard.

Thanks. So far I am finding 69s and 72s for sale. I'll ask the sellers.

Front disk brakes were std equipment on all light duty (1/2-1 ton) GM trucks in '71. Dodge and ford only offered them as an option.

I don't believe it woulf be a difficult conversion if you found a truck without them. But it would probably be eazier to find a truck that already has them.
