Another front brake upgrade question

[Texas275]

I am going to upgrade the front brakes on my 78 to the 11 inch rotors. Instead of a big layout of money for a full kit, I need to break it up over time buying components one at a time. I have found rotors and brackets, my question is what calipers and brake lines would I need to get. I know GM metric, but off of what year, make, and model?

Thanks in advance, Tom

Welcome to the site and group!

I still run the stock brakes in my car so I'm not 100% sure. For some reason I think they're from the late 70s-early 80s Monte Carlos - but I definitely could be wrong. Hopefully someone with more knowledge than I will pop by soon to lead you in the right direction.
