I haven't run the power wire from the firewall distribution block to the core support dist block yet, but other than that, its all ready to go.
Still plan to buy an H4 European style bosch headlight conversion kit for the truck yet, both sealed beams have one of their beams burnt out.
I have an H4 kit in my 77, without the relays, and dang is it ever nice! Can't wait to see it done up with the relays!
