Hi. My name is Jim. I just become a member.I have a question to ask you. I deleted my my heat box with a ac delete box. Problem im having is this does not blow any air to any vents hardly at all. Im heading to a junk yard to get heater box parts that i destroyed. I seen what you did.but would like to know how did u piece the cut outs you did.Looks very good. Is it fiber glassed or did you cut pieces out and fiber glass together? Jim. Email is jimmerjimjr@maqs.net. or jimmmerjimjr@yahoo.com
