my 76 charger had the one that looks like a GM one.

same as the one on my 85 truck,same as my 79RC also.

all mounted about the same on the SB and used the same brackets and spacers.

do you have the bracket that goes on 2 of the t-cover bolts for the pivot bolt support?

there is a tri-angle piece that goes with the bracket on the pump with spacers, the slide adjuste peice.

I will take a look and see if it is all there on the spare SB pump I have,may save you a couple bux if you need it
