Front Calipers Siezed

Need help...My front calipers are siezed onto the brackets with that stupid pin. I tried everything to loosen them up, even used tried using a torch to break them loose. I need to buy new loaded calipers, but Subaru wants $305 each. I can get the calipers from Autozone for less than $60, but no brackets. Anyone know where I can source out some brackets.
Thanks,
