The stock Buick frame is only incidentally & loosely tied to electrical ground via the body mounting bolts, and the body isn’t especially well grounded to the battery negative terminal, either.
I “hard grounded” the frame to the engine block & battery using super-sized AWG-8 wire and lugs that were crimped & soldered.
Now, my gas tank & fuel pump will have a solid, low resistance ground path back to the alternator & battery. (I'm installing new, extra grounds to the frame, back at the gas tank).
As far as the fabrication & connections go, I attached one end of the new AWG8 ground to the same bolt on the engine block, that the negative battery cable connects to.
On the Passenger side "A" control arm (or more accurately, the frame bracket or spring support), there already were a couple holes present. By slightly enlarging the hole to 5/16", I was able to tap it 3/8"-16. A short, flanged head bolt securely attaches the new AWG8 there.
