I was given an unfinished T bucket project with a tube front axle and Harley spokes like yours, Chassis needs radiator mount brackets, Trans cooler mounted then Paint and final assembley I wonder how it will handle ? ? There are things not easy to fix. Theoretically center lines are supposed to line up and some have off sets. Line thru king pin, line thru tire center, thru tire contact point on road . Line on road parallel to direction of travel thru contact point. Using different size tires and wheel offsets that the suspension was not designed for can cause problems.
