Hi Vipertec, nice looking car. As far as i’m aware my GTX has the same calipers as your Bee. I actually live on the south side of town. I picked Roger up from the footy when he was over here visiting, and i think he had a couple of bevvies, so his sense of direction may have been a bit off.
There’s a place called ELKO performance in Croydon that brings in a lot of Mopar parts. This is there website
https://elkoperformance.com.au/ Paul is the bloke that runs the place and has helped me out a bit in the past. I actually bought some a/c pulleys and spacers from him that he had collected in his workshop over the years. Just happened to be the exact ones i needed, so it’s possible he may have some used calipers laying around. Dunno who’s doing your car or where, but if you need to look at anything i’m in Beacy out past Berwick. These same year cars are very close in most of their driveline applications. Mines a 440 auto factory a/c car. Cheers, Glenn.
