Quick update: I cut out the frame sections as per the instructions. During this procedure I accidently touched the "spinning cut off wheel" on my grinder to my pointer fingure knuckle on my left hand....After the delay in getting that fixed up I was able to tack the replacement spring hangers in place and test fit the axle in there. Fits fine - I did position the front spring hangers about 1/2" rear of the stock location. Just to help with a little more clearance between the front of the rear tire and wheelhouse/fender area.

Looks like I will have to run a 1" wheel spacer though to get the tire centered where I want it. Once centred I will have about 2" of clearance between the spring and tire as in the pic - The tire to fender lip clearance will be about 1". The main constraint for bigger tires at this point will be the frame to inner fender space. The other pic is of the front Crites spring hanger tacked in place in the frame rail.

Once i get everything in there and fitting properly I will post all of the measurements to duplicate correctly the first time (with and without wheel spacers) if anyone is interested. Rim backspacing, Rim width, axle width (mounting surface to mounting surface on drums) and tire size with a completed pic from the rear.
