Heater questions again plus master cylinders

2001-08-29 by Bob Magnotti

MarcosManiacs,

Does anybody happen to have a picture of how / or what attaches to 
the bottom of the firewall that attaches the fresh air intake to the 
heater box?  Is it just some sort of bracket that attaches a hose or 
is there some sort of plenum?  On my car the Smiths heater box  is 
mounted over a 6 inch hole that is cut in the firewall but I cannot 
see where anything was attached to the hole in the firewall.  

Another item that i am concerned about is the master cylinder box.  
When I purchased my car I discovered that large amounts of heat would 
blow through the large hole in the firewall where the pedals come 
through.  I solved this problem temporarily by stuffing foam rubber 
around all the edges of the box.  Once I did this the car became 
almost comfortable to drive.  What solutions have other members of 
the group come up with to seal this area of the firewall?
