['68OrangeSunshine]

My '68 C/10 w/292 L6 is also a Fremont [Z] truck and had Calif. emissions A.I.R. gear [once]. I thought the bracket was on the passenger side and Power Steering brackets were on the drivers side. But I could be wrong, it's happened before.
Anyway, save that bracket as it might be useful if you to add want P/S.
P/S is a rare feature on trucks w/ the 292 L6, as most of them were fleet trucks or ordered for other no-frills occupations like agriculture.
