Bah! WHat's with all this copping out and buying stuff? BUILD IT or rip it out of something! I got my 80's Chevette core for a measily $10 flat! You just need some destructive tools for the 10min job; Hammer, tin snips or something to cut heavy plastic, a nice crowbar.
1)Open the hood
2)locate the blackish plastic air casing on the right hand side of the fire wall.
3)Look for the 2 exiting fluid lines
4)GENTLY SMASH away some plastic around the box and it shall reveal the prize!
5)Carefully pry away any material in your way of shaking it loose
6) Cut the lines and let anti-freeze drain out
7)Take that mofo out and then lastly...
8) Take out a screw driver and go to town with all the FREE hose clamps from various cars around etc.
Oh yeah and go EARLY!!!! Nothing like hammering away in a dirty, 100 degree junk yard that opens and closes like bankers hours!
