seat heaters in a '72?

[gaspass]

Has anyone ever done this? How hard is it? As soon as they arrive I'll be putting new seat covers on my 72 Blazer seats. I was looking on E-bay and for $180 for both front buckets I could have a nice cozy winter ride. I figure if I'm going to do it, now's the best time. Does anyone know if $180 is a good price for these heaters, or can I find a better deal? Are they hard to install?
Thanks, Gaspass

I've got a Kenwood 600 watt seat warmer heater going under my passenger seat. I'm saving the Alpine heater for the drivers seat.

Seriously though, you should post the ebay link if you want more opinions.

seemed like i saw them in a dodge diesel catalog, they were a universal type deal and they were $80 each
