I have a tail from a 77 930, which I bought to comply with the local tarmac rally regs. I'm now in another class hence it's for sale. It's genuine, constructed from fibreglass bonded to a steel frame, must have been a bugger to manufacture. Has the larger cut-out for 77-model air con. Pics attached.
I am in Sydney Australia, email me on

Cheers,
Gordon
