ez..I put a mini alt on the 440 truck in the sig pic
use an external regulated one and just crimp on eyeloops on the feild wires and trim the plastic off the batt wire
thats it...the stock VR will work and it is a bolt on
mine worked with the BB non a/c brackets and pullys
i fliped it over and used the single lug for the pivot..which moved the batt post out away from the head( they talk about grinding it down to fit)
I used some spacers and a long bolt thru both lugs as a slip adjuster
I had to make the swing are a couple inches longer was all
kinda tight at the feaild wires on the BB head and VC lip,but clears and lines up stright
there is a template in the archives you can print out for a small block swing arm
and IIRC flipping it over will do the same for not grinding the batt stud down on a SB
