yeah your going to have holes where the cranks went.
maybe fab something out of metal to cover the holes????/
A shop could recover them but seems like alot of trouble if the panels are in good shape.
I think I would hunt for a machine shop to make up a couple plates out of billet to screw over them.
Maybe a pony etched into them or something along those lines.
I'm looking into this also for a capri I'm building except I'm going to use the capri cats head logo with capri etched into the plates.
My panels are perfect except for the crank hole.
I got a quote for 75.00 for both plates if I made the design or 135.00 if they make the design. Seems kinda high but It's still cheap compared to destroying a set of super nice panels that are original black panels from a black magic car.
Maybe this will put a idea in your head.
You might also look at a satinless plate engraved would prob cut the cost in half and could be done at any engraving place at a local mall.
