Hi everybody
When I bought my car ( it is a 1970 Firebird Esprit ) it came with the heater and blower removed. And in place is a heater motor from a classic Austin Mini
Like this one


It works fine but is not right

So I take it I will have to re-cut these areas in red on my firewall/bulkhead


Does anything else have to be cut on the firewall/bulkhead ?

I also have this, will this be the correct one for the inner heat box


I will need to get the inner and outer heat boxes but will it be for A/C or non A/C
I am not be bothered with having A/C but don't know if they are interchangeable with the bulkheads/firewalls

Thanks Guys for any input
Mick
