Dan it's your Zed and how you drive it is down to you ~ won't be getting a lecture about how you drive from me. Been there & crashed a few cars myself.
Have you looked in the for sale sections on here?
Shades RS, zmanalex, Clark Motorsport, R35LEE and a few others I'm sure I'm forgetting are all breaking Zeds. Pretty sure between all of them you could get the parts you're after to repair your Zed.
Might even come in the same colour as your Zed is now too so won't need painting.
