Oh thanks! It says hydra matic on the bottom of the pan and my truck is a 1971 C20934...if you need anything else just let me know where to look and I will post it.

I went ahead and replaced the vacuum modulator since it is so easy figure it couldnt hurt. Will post an update after I drive it here in a few...thanks again!
