On my 86SS I need to install an intercooler inside the front air box as close to the outside air as possible. The SS has the sealed airbox which I've already cut the bottom off so I can get up inside there. However, there is a small support frame which connects to the radiator bottom support beam, then curves up to connect to the front clip airbox, then it goes up to the underside of the nose in the middle. It also acts as the hood latch catch.
Does anyone know is this can removed entirely or does it support the center top of the front nose?
It would have been a lot better if you removed the nose instead of cutting out the bottom of the airbox. Cutting it weakens it and takes away rigidity.
If you discard the center brace, which runs from the top of the core support to the bottom of the core support, then the center of the nose will be unsupported, since that center brace also connects to the top plate of the airbox, and this is what the nose is attached to. You might get by with removing it and your nose center might not sag. I guess only time will tell.
Funny you should ask, since I just got in from removing the airbox and center brace and sandblasting them. Taking the nose off makes everything 10 times easier to get at. It's a lot easier than people imagine. I'm 66 and had no trouble at all removing it by myself.
