Egg crate rattle

[Mad4slalom]

Anyone had an issue with rattly side egg crate fender vents on their 70/ 71 or 72 vette? I have had a weird noise , if I give the throttle a blip in neutral up to 3k . I thought it sounded a bit like a belt slipping or a rough alternator bearing maybe. I actually think it is that the side vent is loose and rattling in its mounting I had previously plugged the top screw holes as the screws were not tight. I can mke it rattle by tapping the vent or front of the ali rocker panel cover. I am thinking of removing , putting some 3m double sided badge tape in the recess and re screwing it back in. Any thoughts? tiA

The vents are secured with two top screws, accessible from outside and a nut on a stud at the bottom, accessible from inside the engine bay. I've always found the nut (and spring washer) a particular pita to fit - maybe yours are missing? With all the fixings in place I've never knowingly experienced a rattle, but there's usually much more raucous noise going on! A much easier to assemble design would have been to replace the stud with a peg engaging with a slot while retaining the two external fixings - although this might have been more inclined to rattle.

Two screws in the top and a set screw from below should keep them from rattling. These were some originals that I had just painted and shows the location of the three fixings.. the pin-stripe masking tape took for ever to apply over the chrome edges

Can't ever sell red mate. The yellow one is down south somewhere now.
