Wanted 305mm GTA calipers

[Cowie]

G'day,
I'm looking for the smaller calipers that suit the 305mm discs that were fitted to the earlier 147 GTA's, and 916 GTV's I believe. It doesn't matter if the discs are worn/damaged/non-existent, I can sort something out. I'm trying to fit the calipers under a 15 inch wheel, as a general rule a 12 inch disc and caliper will fit under a 15 inch wheel. Caliper clearance to wheel spokes won't be an issue either, so long as the caliper fits under the inner diameter of the wheel.
I also have a whole heap of stuff that I have stripped out of a 147 Gta that I won't be needing, mostly interior stuff if anyone was interested. Passenger seat has already gone.
Many thanks !
