I just did this upgrade to my 65. While the two ports are different sizes, I used adapters to run the original 1/4 inch line to the front, and I ran a 1/4 inch line for the rear, but adapted it down to the original 3/16 inch rear brake line where it originally tee'd off from the front line.

For the 1/4 inch section from the master to the rear 3/16 inch line, the 72 inch Poly-Armor brake line from Advance Auto was just right.
