help with ID of this clutch fork and z-bar

Fork is 10 1/2" overall - z-bar is 7" tube. These came off '68 A-body 383, A833 when we replaced with correct linkage. They appear to be a carry-over from when this car was a slant 6, 3 spd..

Fork seems to be what Brewer lists as for 63-66 A-Body small blocks or slant 6, but this z-bar is an unknown if anyone has some insight. I'm going to offer up here or e-bay if anyone has a use...thanks.
