If I were you I would send that BK jacket over to Johnson Leathers in San Francisco. Tell him what you want taken up and they will knock it out of the park. You don't have to send it all the way back to BK. It may take 2-3 weeks max. First off, Johnson Leathers makes killer leather jackets and have more than enough skills to do this. I got them to resize a jacket for me. I was like, no way they would be able to do it. It turned out awesome. You couldn't even tell anyone took it apart and fixed it to my specs. I will be ordering a BK jacket soon. That will be my plan if it doesn't fit perfect.
