'69 340 Sanden with Bouchillon 4735 Bracket Kit

There are issues, but there are fixes:
Classic Auto Air Belt alignment fix
That is for the '70 and up bracket belt setup. I am asking about '69 and back which is completely different and not related to '70 and up. I already seen that thread and it does not apply to the '69 and earlier cars.

'70 and up diff belt routing, diff pulley setups, diff pulley offsets, diff water pumps, diff AC bracket kit, diff crank pulley offsets, diff everything from the '69 and earlier cars.

So any solution related to '70 and up small blocks is useless.
