The cost of my order was $120US not including shipping, I ordered 2 sets of Brembo caliper rebuild kits, master cylinder rebuild kit, and a timing chain kit for the '84 LS .
The price of just the master cylinder piston, not even a kit, was $65 here in the US .
From the looks of it, I don't expect to place another order with them for a while, but when I do accumulate enough needed parts, I will check them out before going anywhere else .
