Just tossed in the seat heating/cooling system from leatherseats.com. Pricey ($350 per seat), but the cooling is very worthwhile in TX.
The only thing I changed was upped the power wires. Each seat pulls 8A on max cool, but the power wires they provide are 20ga. Note that these are Procar Rally XL seats, but the process is pretty universal. Should work just fine on the stock seats. Maybe even easier since there's so much more room in them.
Only thing left is to figure out where to put the switches. They'll probably end up on the sides of the console somewhere.

 

Nice work! I just got heaters for the buckets that I'm putting in my 67 Delta. With cloth I don't really need cooling.

 

pretty cool thanks for posting

 

Now that'll blow smoke up yer butt. Very nice work.
