[DeTomaso] aftermarket heat-A/C unit

[The Goyaniuks]

In the Canadian East the summers are hot and humid
 
Like you, I was never really happy with the stock system.   But I still wanted to retain the original engineering for ease of installation and servicing.
 
I am putting a 4.6 in my car.
 
While at it ...  I decided to replace ALL of the A/C gear but using the stock set-up.
 
I replaced:
 
1)  the stock A/C evaporator from a 4 pass unit to a 6 pass unit (fits in the same A/C box).  The heater core is retained - need it in Canada !
 
2)  the stock fan unit to a quieter and stronger 3 speed Spall fan unit.  I found the stock unit did not blow strong enough.
 
3)  the A/C hoses and fittings to new hoses with O-ring fittings.  I was tired of refilling the A/C system every 1-2 years.
 
4)  the condenser from a 2 pass unit to a new 4 pass unit.
 
The 4.6 came with a new and modern compressor so I gave away my rotary unit for the Cleveland.

I have the vintage air heater unit for mine. I don't plan on using A/C at
all and I just wanted a heat box. They have a lot of options but I really
don't know how well they will fit.
