Where does this electrical box go?

Looks awesome Rob! 1st pic is.voltage reg. In dads 67 cuda it mounts on the firewall drivers side. Just to the outside of speedo cable I believe.
Intake...thats an LD4B? With dads I had to use a 340 6 pack coil bracket(repop)
There is a member on here that makes them or you can mod one up yourself.
Check out 6pk2godemon thread on her 4bl swap. She used an LD4B and a home made (very well) coil bracket.
Looks very sharp!!
