Brake hose fitting

[catch2otwo]

So I purchased the stainless steel hard brake line kit from cpp. I also purchased their rubber brake line that goes to the caliper. I informed them I was using '77 calipers as I was doing a power brake conversion on my 68. The hard brake line threaded fitting is smaller than the female threaded hole on the rubber brake line. Id rather buy new stuff before I have to talk to another tech from CPP.

Is it possible to bring my hard lines to a brake shop and have them cut the ends off and put new fittings on? The other end of the rubber line with the banjo bolt seems to thread into the caliper just fine so the only thing keeping this project moving is threading the hard line into the rubber line.
