Heater upgrade backdating info
 

Search the past and couldn't find anything. I have asked this before but want more detail if possible.
Taking the heat of the fan shroud and replacing because of the SSI upgrade. Back dating from a 74 on a 81 sc.
Can anyone give me some detailed diy on the project?
I will then add it to, and use it with, what i do and create a tech article on it with pics.

Thanks,


Pics of the cars comming soon guys.
