i'm going to the junkyard tomorrow to pick up some ground effects that i need to finish my car. what's involved in removing the rear quarter and rocker panel ground effects? what tools will i need, and if i need different wrenches or anything, do you know what sizes?

------------------

 

I think (if I am remembering correctly) they are all 10mm screws and 13mm nuts. The rear quarter pieces are attached to the panel and the rear bumper cover. The rocker piece is attached in the door jamb area and underneath with about 15 fasteners.

Currently installing 3.73's into my 9 bolt (YES, it is a 9 bolt & YES they are 3.73's, not 3.70. I currently have 4.10 gear sets and new series 3 posi carriers for sale for 9 bolts )

If you want the mounting plates for the rocker panel ground effects also, that's where things get tricky. They are spot welded to the car just beneath the doors, and you'll need about a 5/16" drill bit to drill out the spot welds. Titanium Nitride coated bits and cutting fluid are the way to go there. That's only if you need the mounting plates though.

 

can they be installed without the mounting plates?

 

i've heard that without the mounting plated the gfx will sag...
oh and i have a question myself...
can i take the mounting plate of any firebird with ground effects?
cause i have the 91-91 gfx,i just need to put them on...but i need the mounting plate, but can i take the mounting plate off a firebird that has older ground effect???
thanks

 

Does anybody know if the mounting plates are differnet from 85 - 90 and 91 - 92. I have a 89 RS and wanted to change to the new style ground effects but not if I need to do welding.

I wouldn't think a person could effectivley mount these effects without the mounting plates, as I'm positive they would sag. As for the 85-90 to 91-92 difference; yes they are slightly different. The 91-92 style has a bit more of a belly to them but I don't think it makes too much difference. If the holes line up it'll work, and I've heard of folks changing over to them with no problems.
