torana68 -thanks for the info. any idea for the brake differences?
OZ sold A51 and A52 are JDM std (skinny discs, 2 piston calipers and small drums), GA and GB same as A51/52, dodge colt early same as A52 but with 9" rear drums. later Dodge has LA/A72 Lancer style front calipers/thicker discs and the 9" drum, JDM Galant GS has brake booster, not sure what combination of disc/caliper/drum, 16L Galant is same as A52, 16LGS has a booster etc etc etc all very confusing then there is the Lancer variations, GTO's I think same as Galant GS?
edit OZ Galant station wagon has the 9" drums, Dodge/Plymouth/Galant GS/GTO have a brake failure switch as well
