Just installed my evaporator....instructions are pretty vague...on the outer side I used the hood bolt. I used a longer bolt from the outside thru the weld nut and used a nut on inside and added the bracket to that with another nut. On the firewall I had to drill a new hole as mine was filled in by PO. also I didn't have the blower motor hole and had to drill new 4 " hole for lines all in all it turned out great. Send pm and I can text pics
