MINT swallowtail. Nice work, mate. Only just spotted this thread!
The early 76ers were built in Aus and painted in Aus too (obviously), from what I know. I would imagine it is a Dulux colour as mentioned previously. I am not sure what colour that is but I may be able to ask a mate if he does (or Jace can.. 'cause he lives closer :P).
Nice work mate. Pity I didn't see this earlier. I could have offered you Weitec coils. :)
Let me know if you want to sell that auto box and all the gear (floor shifter, cables, mounts etc etc). I will most likely take that bad boy off your hands. :)
