I have a 89 ranger cab sitting in the wings just for that purpose. Plans are at the moment...
A couple of pie slices in the floor and roof to pinch the body to the close dimensions of a model A cab width,
stand the windshield posts up vertical, flat glass windshield,
lengthen the roof to make up for the extra length because of windshield placement,
make a visor from the second roof I have for it,
incorporate a model A cowl,
and of course chop the roof.
And the hardest part of all....make it look cool and not like a clown car.
Have pretty much what I need for it in parts, just need the time to get at it!!
My Avitar is the intended look and inspiration, we'll see.
