Haha,
Yes you’ve arrived at the good part! thanks for checking in. I’ll be one of you guys some day with all the bronco advice. i’ve really enjoyed it when it’s done and it works but the middle part is not so fun. I will fix up Masons (kids) speaker wiring and maybe call it a wrap for a while on the work until I get around to the suspension lift. I want that slight rake back to front and a slightly fatter tire on there. I was hoping I could find a 1.5” front and 2.5” rear solution without variable rate springs.
anyway for this WH “one wire” alternator in which some people run 2 wires
here is what worked on my mostly stock 302 engine:
The #6013 alternator (
https://www.wildhorses4x4.com/product/Hi-Output_Alternator_130-Amp/Bronco_Starters) is an actual 1-wire version of the standard 130a 3G
#6025 wire and fuse kit (
https://www.wildhorses4x4.com/product/Battery_Charge_Cable_AMG_fused/Bronco_Starters) uses 6ga battery cable and a 175a Mega Fuse.
This alternator mount from CVF was expensive but nice because it has a rod with two fisheye sockets you can twist to get the belts as tight as you want and the position won’t slip. and it looks nice.
302-ALTBRKT-D from cvfracing.com
and this two groove alternator pulley which was the hardest part to find
this specific pulley matched the black color of the WH water pump and crank pulleys and it has 2 grooves and it was the right offset from the alternator to align to the other pulleys.

Then....for my bronco - which only has the alternator, original EB 302 water pump
and power steering..WITH the WH size water pump and crank pulleys which I am told are stock sizes for the 302
you should be able to use these two belt sizes (or something close) which I had to discover by trial and error:
Napa #7385
Napa #7565
Thanks to advice from Paul (aka other Doug) I ran the small belt on the inside around the inner most alternator pulley groove, water pump and crank
and then a second larger belt that goes all the way around and uses the 2nd alternator pulley groove. That larger belt goes around the water pump, to the power steering and around the lower crank pulley..
