GingerNinja I don't think there is such a thing here. Plenty of places have worked on my 240s over the years but I often chase parts from overseas or Berry in Melbourne.
volvodriverman You could try performance automobiles if you're feeling particularly deep pockety. Autocraft would be the most likely otherwise to have at least some idea what you're talking about.
GingerNinja I've had work done at Autocraft and it's been really good. I work in Kingston now so I'm getting Kingston Auto Repairs to service my cars. They always have interesting old race cars in the shop and I've had good work from there over the years.
