I currently use an ACDelco 63A 10 SI, P/N from Rock Auto, alt P/N 88864305, plug clock @ rear view 3 o'clock. $57.89 w/$25.00 core charge ($32.89).
It powers everything fine, but I have a mechanical fan and no high power draws like high wattage stereo gear.

However, I have notes in my spreadsheet that if needed I can upgrade to 85A 15 SI, ACDelco 334-2128 {#19135686, 88863357} or 78A 12 SI, ACDelco 334-2156A or 335-1094, 3 o'clock.
