Drilling holes in the fire wall of my 39 chevy

DONE I am re-doing the firewall on my 1939 Chevy two door Sedan. It had home drilled holes for aftermarket heaters, so I filled them all in & now I need holes in the correct spot for the original 1939 Deluxe heater. Does any one have the measurements? DONE

 

After 70 years there are bound to be a few extra holes here and there. Unless your doing a restoration, I'd fill them all and re-drill your own where ever you like.

 

check out where the heater hoses are on my 39 sedan.They in the stock location and hooked to the factory heater. Mel
