I’m not crazy enough yet to test that JB weld theory lol.I've not looked into how well JB weld holds up to heat cycles, but wondered if a couple horsepower couldn't be found in filing those air holes?
Also, have to know of you plugged the pets in the back with shortened books like I did. It's been 21-22 years since l had a thermostat stick causing a blown head gasket. That led to a port/polish on my E7s.
Thanks lolNot sure on the Molding, but cool tat.
I have nothing in there right nowWhat do you have in there now? Might need to get a new./used one from a junkyard.

Mine was completely destroyed , I’m going to have to figure something out.I looked and looked for the same piece and ended up gluing my original back on. Mine only had one small nick out that is tough to see. I did buy a "T" style that I split in half to tuck under my upper windshield trim. It's barely seen but fills the gap. What I used was actually half of the trim I bought as I cut it down the center.
