The blasting gun I'm using is a little $50 Blackridge kit that I found at Super Cheap Auto, I have it hooked up to a fairly substantial Clisby Air Compressor.

May very well have been rebuilt at some stage, it would certainly explain the excellent condition the mechanicals are in and the C69 Flathead

unfortunately I know very little about the Trucks history other than my mother recalling it sitting in the local mechanics yard for some 30 years. knowing what he was like as a mechanic it could have been cobbled together out of whatever he found to keep the tow truck running however the mounts etc are far too factory for his handiwork.

Thanks for the info mate ill have a look at the diffs over the weekend and see what's on them

Thanks Nathan,I will give Supercheap a go tomorrow, and look for a Blackridge kit. I have a near new, engine driven 3 cylinder Clisby compressor. I am counting on it keeping up with the short bursts I will be using it.
Mike C your helpful comment on the cabinet blaster has made me think about the bead blaster at work, that little thing has done years of glass bead blasting. I think if the Blackridge blaster doesn't do the job then I will get a bead blaster hand piece and modify it to a sand blaster.

The key to blasting is you must have a compressor that will keep up with the air consumption and maintain 100psi / 7bar. Obviously a large resevoir helps but even blasting small components will empty a large resevoir amazingly quickly. Once the pressure drops you are just making dust to no real benefit.
