CamaroBob87

I was hoping someone could help me with this. I've done a bunch of research but I cant seem to find what I need. I have an 87 Camaro that I swapped a 9 bolt Borg in with the aluminum calipers. I ordered a set of premade stainless lines for the car with the Australian 7.75 9 bolt. All the lines fit perfectly and connect to all my hoses and master. The 2 lines from the master to the proportion valve fit as well. Now the rest of the lines are a different thread on the bottom of the valve. The valve is set up for fine bubble and all my line have coarse bubble ends. I really don't want to start hacking up my lines. Is there a different valve for my application? This is the final piece of the puzzle for me to drive this thing around. Any and all help appreciated. Thanks.
