I agree in part Max, but I think MF is like me and if he can! All original is his go to for restoration or preservation jobs. The vortex is a different casting than the regular 80's series casting of deck. Well at least my red one is, I haven't looked under the cowling of the yellow one. So the deck in the gumtree add you posted the link to won't work. I say keep looking and because I have my original red 83-84 vortex, the next one I find with a good solid deck already has a home before I even find one! Looking at you MF!!!
