bus heater!..
I took an old school bus heater that went under one of the rear seats ,and mounted it in a wire milk crate for the rear of my 72 K5..it would melt snow off the roof at the rate of 6" in about 10 minutes,and with a 195 thermostat,I never was cold in it again,ever!..
My friend had a 73 Volvo 144,its heater blower motor seized,and the heater core leaked too..so he bypassed the hoses..it was going to be an "all day sucker" to fix,because Volvo must have put the blower and heater core in the center of the car,and built the car around it!..he liked my bus heater in my Blazer,and decided to make one similar,after balking at the 125+ dollar price of a "under seat" heater from the "Zero-Start" catolog..and didn't feel like taking his entire dash apart,and paying big bucks for an oem heater core and blower motor..
He simply used an old GM heater blower motor and fan I had lying around ,from one of the many vehicles I parted out,and mounted it in one of those marine battery boxes we sold cheap at the parts store..just cut holes in it for the fan,2 defroster hoses,and had to hole saw his firewall to let the heater hoses in...it threw a TON of heat,but it wasn't pretty!..after living here in the winter,you tend to not care about looks when its only 10 degrees out for months!..(car was a junker anyway,and wasn't really worth fixing "right")..he kept the "heater box" after he scrapped the car a year later,and used it in his next "beater",a 67 Impala ,mounted in the trunk!..
I'm sure those factory built ones work great,but for the price they get for them,they'ed BETTER!..
--I say get some plywood or a plastic tote box,and make your own,or go see if the boneyard has any school busses(most have a lot of them)..
