Cool project !
What are your plans for that (gross) stock instrument clustre ?
I'm with everyone else here , in regard to moving the axle 1" , but for a different reason :
Chrysler engineers set the axle forward-of-centre for a reason : traction ! And the avoidance of spring windup . By placing the axle where they did , prevented wheel hop and spring windup under hard acceleration .
I wouldn't mess with that design !
More subtle colours are advantageous ; in this case it'd be easier to keep a close-to-factory-applied colour so that you wouldn't have to paint the doorjams , trunk , underhood , etc.
Besides , that gold looks great -- imo -- when it's 'fresh' and glossy .
I love your wheel / tyre combo . Nice , vintage equipment .
