Help ID master cylinder

[Jeff S.]

Delco assembly, casting number 5460346, 1-1/8" bore dia, deep-hole rear piston, front outlet port has 7/16-20 female thread; rear port has 9/16-18 female thread. Two bleeder screws. Machined boss on side adjacent front outlet stamped '2067'. Machined pad on nose stamped 'HK'.

I thought this was correct for 72 Corvette w/pb. Can anyone confirm or otherwise ID? Thanks in advance.

The date code indicates it was manufactured on the 67th day of 1972 (March 2, 1972). However, the "HK" code is not, as far as I know, a Corvette code. Are you sure it's not "MK"? "MK" was used for some 1972 Corvettes with J-50. If it's, for sure "HK", then I don't know what it's for. Keep in mind that the 5460346 casting was used for other non-Corvette master cylinders.

On closer look (magnified), I think the stamp is indeed "MK". Thanks.
