hey all,
I am trying to figure out hole sizes and locations that should be in the firewall for a 1971 cuda with a non a/c heater box setup.
car firewall was a a/c equipped car, but since patched and filled over. no holes for blower motor or hoses.
anyone have a scaled layout or template showing correct location and size for holes in firewall?
I have found a few pics and have got close, but I don't want it wrong,
does someone sell a half firewall new steel panel?
also I was just going to hole saw out hole for motor,
but have notice some seem to be more egg shaped.
should it be round?
any help would be great.
thanks
