Other sources for dual piston calipers?

[el shawn]

HI,
long time lurker, first time poster.
After a long aircooled hiatus, I have returned to the light with a '68 notchback. never being one to leave well enough alone, hopefully this winter will see a 2275 in the back, a substantial altitude adjustment and while I'm at it a brake upgrade; the stock calipers are siezed, so i might as well right?
So then here is my question, what are some other options for dual piston calipers? I can't really afford to roll with porsche stuff so I'm looking for a more econmical option. I am thinking of using some A2 jetta rear calipers for the rear end, but I would really like a pair of twin pots up front. i seem to remember hearing some Volvos had them but I am unsure.
Any help would be greatly appreciated.
Thanks,
Shawn
