yeah I really explored my options and since I already gutted behind my dash and all last year Im better off just building a heater box behind my dash from scratch. I'l buy a small heater core from pepboys, build a box and mount a lil highspeed fan on it with two ducts going up for defrosters and maybe two ducts going down for feet. The only issue I can see is the little fan not having enough flow to push the heat through 4 ducts so worse case senario i'l just run them to my defrosters. Winters coming she's not my daily driver but I would like to have the option of driving her whenever I want compfortabley. Within the next couple weeks I should have a cool lil setup, others can work with my idea and maybe even make there own. I'l let you guys know how I make out, pics and results coming soon.
