Sorry to semi-hijack this thread....

BUT.... .....what's the difference between SVT radiators w/ A/C and w/o A/C other than an extre $50? I'm guessing that the one w/ A/C is a larger core to compensate for when the A/C is in use?
(I don't have A/C in my SVT....but if the one w/ A/C is bigger......)
