Thanks boys.
I also got a spare base in really good condition off NY father in law today with a workshop manual to suit. It's a genuine victa twin spare. He made me crawl u the house. Plucked out a twin base. Sane Colour just in good nic.. He had found a twin years back that needed tlc. Ended up shoving it under the house and never got around to it. Still need to find the spare engine he says he may have...

Twin 500 project under way... Il post pics up of the outcome. Il be repainting the Base in orginal colour. And shining up every nut and bolt. I'm fussy I will not dissapoint you all I promise
