Re: A/C to Plain 'ol heater question
I have done this on other cars. Do you have the under dash portion and not the engine compartment side or is the whole assembly gone?
You need to find a square body heater only blower housing and fan motor assembly to start with. I would look for a 73 to 80 as they probably made some changes when they switched the front end sheet metal design. If you need the under dash part get that from the same donor too. Make a cardboard template of the firewall opening of the heater only firewall opening on the donor vehicle. If they will let you do it, cut out that section of the firewall with enough material to cover the opening in your firewall. Use the template to locate the required mount holes and openings in the firewall of your truck. Fill in any areas outside if the new blower housing with sheet metal. I welded in the donor vehicle firewall heater area on one I did and the other one the heater blower housing actually covered the old A/C opening so it didn't require any welding. I don't know exactly what you will need to do with your truck but this will get you pointed in the right direction.

Re: A/C to Plain 'ol heater question
i believe there are differences in the holes in the fire wall..the non ac will bolt up but i believe there is an extra hole that will need to be patched.
Is your truck a driver or a show job?

Re: A/C to Plain 'ol heater question
Yo! Deleted my '76 Camaro's A/C in 2006 and it's opening in the firewall is larger and has a slightly different orientation,...I would imagine that GM did the same with the trucks.
I jumped on the internet 'cause I remembered how to search this out,...search "truck A/C delete" and you'll come up with some suppliers of the conversion heater box that will allow you to use the existing firewall, and factory heater parts to complete the conversion. Try this link: http://www.acdelete.com/pages/73-7_A-Body.htm My pics are gone from the thread, but my old thread about the wiring with a full description can be found at this nastyz28.com link: http://www.nastyz28.com/forum/showth...813#post606813 I sure hopes this helps you! Questions,...don't hesitate to PM me on this board! I'm happy to help all I can. Merry Christmas! Todd.
