67 with 73-87 calipers?

[The Big Green]

Here's the deal, I broke a brake hose to the caliper and I had the parts store bring out a 71-72, 73-87, and nothing matched mine. So, because I need calipers anyways I can pull mine and have them run the part number and get whatever these are or can I use the 73-87 calipers and brake hoses? I have the 73-87 spindles with the 6lug conversion rotors. Thought I'd ask first since something could vary for all I know. I think the rotor thickness may vary?
