OK !! I lost all my firewall/engine pictures of what goes from the engine and or the gauge cluster through which hole in the firewall and with which grommet on the firewall as far as wiring, hoses etc. I do know that the throttle,choke, and oil temp goes in at the top and through grommet item # 3681071 Chevy's of the 40's. Can someone with a 46 1/2 send me pictures or a link of their engine compartment and firewall so I can get everything through the correct hole!!
