I've been looking for a rear 1/4 panel for drivers side a while now. No luck finding 1 here. I am looking to import a bunch of stuff from the US on a pallet inc. 1/4 panels, roof skins, doors, topy steel wheels, even bonnets because they are getting tougher to find.
I'd estimate a good second hand rear 1/4 panel to cost around $1,500 AUD landed here.
If you can find 1 locally for less than that, grab it.
