I have this left over stuff- might be useful so I thought I would offer it before I chuck it.
There is the top half of a 74 seat with cardboard backing piece which is cracked but could be used as a template. The seat is missing the 10mm wide spring steel piece that goes arounf the edge and you will need this before you rehupolster the seat. I beleive you can use spring steel wire as a replacement. I also have the covers for the top and bottom if you are into mega ratty seats.
The other stuff in the photo is a gear shift, rear tortion housing plates, gear selector rod from the bottom of the gear stick back to the first joint and a drag link for the steering which has a small amount of movement that can be felt with your fingers in the tie rod ends.
I am at Blackhead halfway between Taree and Forster and may be able to assist with getting them to you if you are in Sydney or can post at your expense.

tortion housing plates and seat stuff still available

Bump I might be able to bring the seat up to Noosa or in between as it appears I might have some room but wont know until Friday
