New from Australia!

eBay USA's site is pretty good for Chinese replica parts for this era ute, picked up brand new tail light lenses for my mates 1980 Mitsi L200 for $16us or $20nz.
And don't forget being in Oz you have the Courier to pilfer from too

They are starting to get a bit hard to find these days, but if you keep looking they are out there. I think the ford couriers had twin headlight grilles. think I've got a 5speed box which has done about 2000 km since being rebuilt. and also i should have a reground camshaft.
Good luck. Maybe start a build?
