I noticed the other day that the upper portion of the housing that the thermostat resides in is plastic. I believe that I've seen postings on the list about updating to a metal one.
It appears that this is a simple, straight-forward procedure... is it as easy as it looks or am I missing something?
I also noticed in the Performance Parts catalog that they don't sell that piece... is this a dealer-only item?
TIA for the help and comments.
