How difficult is replacing the drivers side window blow out clip / tab on a 1987 GN T-top? What's the process and what tools are needed?

Just started getting a 'pop' noise when accelerating. Possibly a little back-fire but unsure. The noise happens when I floor the car at about 20-25 mph, boost builds and then a 'pop' sound. So I let off. Low mile stock car throughout - stock turbo, injectors, exhaust, etc. Running 93 octane...

Looking for an OEM pair of visors with the passenger side vanity mirror. For a show car so must be mint or the cores are good enough to have reupholstered.

The one I have is scratched and would prefer to replace ASAP vs remove paint replace. Anyone have a very nice one that can part with? Thanks.

Was this sticker placed on all 1987 Turbo Cars on the driver's side visor? Specific to the Grand Nationals: On hard top cars? Astro Roof? T-Top? If so, were there a specific placement from left to right / top to bottom?

Driving on the highway, spedo pegged at 85 (but not going much faster than that)... Slowed down to 60 and heard a clicking from under the dash - drivers side. Spedo still gave accurate (from what I could tell) mph readings. Both odometer and trip gauge working. The slower I went, the slower the...

My 1987 GN was sold in Zebulon, NC at Gill Buick, Pontiac, GMC and I am looking for one of their dealer emblems or stickers. I'm not really sure what they used as advertisement in 1987. I've tried running an add in the local paper(s), called multiple auto parts stores, called the nearest...
