Done. I'm with snake.
I'm hunting this old Revell kit (only the stock version) since years and I never saw one offered in Germany or Europe. They are that rear even in the US and if one unbuilt(!) Kit is offered, the shipping cost are out of the world - not the price of the kit. They are human.
I would be so happy to find a built one, if I get no kit. This 56 will close the gap between the 55 and 57 I have built.
As I searched for the 57 bel air, I found one built in the same condition as your 56 - and I let it as it is. Didn't layer my hands on. And I love this very old piece of modeling in my collection. Therefore, i get a newer kit and build that.
Just my looooong story. Man, i love those old kits with all opening doors.
But it is your choice. I'm looking forward, how it comes together again.
Btw, my old 57s wheels are in good shape. No reaction from rubber and plastic
