68 PlymouthValiant custom interior idea

I'll have to check that Summit out then and see whats on there. Im also looking locally here in northern IL around my area. Just pricing out and for a repaint job. Thinking of the purple that the charger is using this year and maybe some sort of custom paint but nothing too major on it, some kind of striping I saw on a surfboard out in CA. Just can't remember the make of it, saw it at Ron Jons Surf shop at the Block in Orange CA, it was white with a green flake three stripes, all connected at the point of the nose and then connected at the end of the tail, if i remember correctly, lol! Dont' think it was an Al Merrick or a Hobie!

I know 5 x 4.5 but what about backspace? I'm looking into getting a 16" to 18" for it and something wider than the stock ones that i have now.
