That front end should look cool.
It's too bad everybody lives so far apart. I have a frame jig made from 2X3 box tubing tacked together, I checked out a similar frame on it.
At the rear it has 1/2" steel mounts with holes for the 20mm axle and the swingarm. The front has frame shims and clamps. For measuring, I used plumb bobs and a triple tree with a piece of chrome moly tube inserted through it.
