Hi List. With all the talk about aluminum radiators, one issue was 
missed.  With the exception of TR7 & TR8, all the cars from Spit through 
TR6 have a radiator that is a "solid" mount. Aluminum, by nature, can 
not stand any twisting, flexing or "racking".  All these cars are 
body/frame construction.  Frames twist and flex and since radiator is 
hard mounted, so does the radiator.  Another, and we feel better, choice 
is a modern re-core. Our radiator shop use a MaxCool core. Large 
diameter, oval shaped fins with lots of surface for heat dissipation. Ted
