OK, So I got the booster back from a semi-retired guy through South Gleneld Brake Services at Marion Trade Centre (Thanks Guys!) and sent him the pics. He decided that was all too much work and turned up a heat/ impact resistant plastic ring spacer off a BA/BF booster, and machined it down to 10mm thick and drill out the VX booster bolt pattern. He then turned the rear of the booster 90' to the front 1/2 (and tested it and the master- put brake fluid soaked chux in to keep) and just simply redriled the holes in the VP bracket to suit the VX booster bolt pattern, replaced the foam insulation and put it back together! When I put it back in the VP, it fit PERFECTLY and the rod length exactly the same as the old VP. Not only that, but the VP bracket that goes on the front of the master lined up to the original bolt studs so no mods were needed whatsoever in the engine bay!
So happy with the work, I recommend ANYone in SA to go see South Glenelg Brake Service- Next to Specialty Tuning out the back shed....
