Hi mate, I have a front panel I removed from a parts car for my panel van. It's mostly straight, 100% better than the one I had in my car but still needs a bit of work. Might be perfect for an rs tho. Also has the support in the centre cut out. I can post a pic or you can come check it out if you want. I live in the southern suburbs.
The only reason I'm not using it is I just bought a new one from SMCKA. Didn't really want to spend more time doing the few repairs to it when I still have a lot more body work to do with a short deadline. Pretty happy with the quality and the price of the new one. I Can recommend them.
