I've decided to buy a Mazda B1500. It's a 1967 model, despite the 80's boxy shape.
Here's a picture of as purchased:
It's got an incorrect front bumper bolted to the original and an ugly canopy to be removed ASAP.
Interestingly, it has a mod plate and was previously registered in Vic (Aust.) with it's existing donk: a 2.8L Isuzu diesel with 5 speed. It has Mitsubishi disks up front, and an err... Wolseley diff. It's dead straight, and begging for a rat-resto.
It's seems to be a bit of a rare model, in Australia anyway, so any info or contacts for parts would be really welcome.
