Was gonna say, there's a 1990ish seca SX in the local pinch-a-part and one with slight damage selling for $2000 just around the corner from here.. but i suppose that doesn't help seeing as you're in Queensland...
I bent my car around a tree(s) a few months ago, I know what a pain in the arse it can be trying to find parts! Good luck getting it back on the road man!
