Big Block Mopar Isky Adjustable Rocker Arms Wanted

Im looking for the old Isky Adjustable Rocker Arms for a Big Block. I need the ones with the hardened pad that hits the exhaust valve. The old ones before Crane made them for Isky, these wont say Crane on the bottom of the rocker. Im in need of a few sets of these. You can send me a PM .

Thanks
