Marcos Maniacs

Hi Bob,
The attachment for the heater ducting for my car is out of the car 
sitting on the work bench so I will take a picture of  today and post 
it tonight. It is a flat plate with a short piece of 3 inch round 
"tubing" brazed to it.  No big thing and could be replicated easily.  
The early Marcos cars (Like mine)had a fiberglass box that completely 
enclosed the pedals sealing out all the heat.  The box had a lid for 
servicing the master cylinders.  I'll take a picture of that and post 
it this morning because the car is at home (the heater attachment is 
at the hanger)
