'New' Bedford truck

I cant see I've laid my hands or eyes on a commercial bumper for some time, but im guessing it different. Its a fairly solid bumper and im thinking would also be a bit wider than that required for the HQ-WB.

It's funny you mention poor seating and poor suspension because both are a vast improvement on the k model. I'm just over 6 foot in the old money and my old man couldn't work out how I managed to drive the k. This one, however, is quite comfortable. It's only the 214 (higher hp I think) but I think it will be fine for what I will use it for. The HEI really woke the k up so this will be getting the same mods. There's also a multitude of driveline combos available for these things as you have suggested including the holden v8 which was factory fitted to some models.
Whoever invented the tilt cab needs a round of applause because these are not. I'm currently replacing the water pump and it's a complete r-sole of a job.

Will do, considering they were so popular there is a distinct lack of information on these things on the internet.

Pic of the model tag.
Prefix of ID tag is EDLOBJH, which makes it a KC according to the english model guide in holdenpaedia. The next two letters are JH which differs to that recoreded in the guide, possibly something to do with the Australian manufacture.

Limited by revs/gearing. First gear is pretty much useless but were apparently designed to take off fully loaded on a steep hill. For its current use there would be room for a change in diff ratio, what's available and how far the little 214 will push the truck at higher speed would then be the limitation. I do have little supercharger handy though, so that may make it all come together nicely. Alternative to that a Holden v8 and matching driveline is an option and as they were factory fitted doesn't require engineering.
