More 73+ disc conversion questions

Thanks blu, good info there. I have 14" rims so I'm definitely going to stick with what I've got. Unfortunately the guy who sent me the parts sent me everything he had so he didn't have the MC lines either. I've been researching and it looks like I can buy premade lengths of fuel line at Napa and then bend them with a cheap bender and some patience. Hopefully I can figure it out without having to adapt anything to keep possible leaks down.

I'll check the calipers condition too. I just know a lot of the store bought parts are junk so I'd hate to give away original calipers as a core to get a couple of cheap ones back.
