So the GF is taking the 88 5ktq on a little trip for the next 
week so i get out old reliable this morning to drive to work, well looks like 
the heater core is busted after warmup, coolant misting all in side the car and 
leaking on the ground too :-(  So how big of a job is replacing the core, 
where can i get one, and whats it going to cost me.
Thanks Guys!
Britt
