My 91 Formula was missing the spoiler when I bought it - I found one locally for $50 and *fingers crossed* will be picking it up today.

Since mine was missing, I have none of the nuts for the studs and the seller doesn't have them either. Are they plastic studs or do I just need metal nuts for them?

Also, was there a gasket or something to seal the holes in the trunklid? Can I rig something up that will work?

I've never had this wing before so I'm not sure exactly what was used to mount it. I've still got the metal tabs on the sides of the rear glass, but that's all thats left.

Any help would be greatly appreciated.

 

If i remember correctly there is 2 10mm headed BOLTS with captured, serated washer per side.
I used a little 3M butle tape around the bolts 4 a sealer.

 

Thanks for the info - Just got back from picking it up and aside from a crack on the bottom side (where someone tried to take if off w/o sliding it back first), its in great shape. I'm so happy to have the correct wing back on my Formy!

As for the bolts, I was actually expecting a stud on the wing itself, but I see now the threaded holes for a bolt to go into. I'd like to get the bolts tomorrow and get the thing fully bolted on.

Can anyone verify that an M10 is correct (and what thread?)? It looks physically about the same size hole as a 1/4-20 bolt.

Can anyone verify the actual length of the bolt I need as well??

Any help would be great so I don't have to lug the spoiler into the hardware store with me!!

Anyone?

 

IIRC they should be the same as the body panel bolts (M10).
Correct me If needed.

 

they are 10mm, coarse pitch, 1.5 i think about 1" (25mm) seems to work, thats what i used to mock mine up with.

 

Thanks for the info. I'll try to pick some bolts up after Christmas and get it bolted down.

Thanks!

 

The studs screw into the spoiler, then the studs drop through the decklid and you thread on the nuts...

The dealer or an auto body supply house would be the best place to find the studs new. Otherwise, hit the junkyard and rob a few out of any GM car...

You might find that the holes that the studs screw into have been stripped out. In a pinch they can be glued in with JBWeld or Epoxy.

 

regular hex bolts will work too, but stubs would be ideal

 

Well, apparently, the bolts/studs for my spoiler aren't 10mm. Picked some up both 1.25 and 1.5 thread and the bolts look more like 8mm. Definitely not 10s.

 

sorry about that, i brain farted, they are smaller than 10mm, but you use a 10mm wrench on them. I will have to check, but they should actually be 6mm. I have a pile of them laying around, and im pretty sure thats what i used.

 

If you can check, that'd be great - If not, I may just swing by the hardware store today and grab a few.

Thanks!

 

I had to swing by Home Depot to exchange some stuff and bought some bolts today. The correct bolt is a:

M6-1.0 x 25mm

Thanks for steering me in the right direction on the 6mm. I've gotta do a little sanding on my repair and then I'll get it bolted on!

 

Can anyone help me? I need some advise on how to install a 4th gen 2001 trans am spoiler to my 91 firebird! I dry fitted the wing and can clearly see that I'll need to do some drilling through the hatch for this to work! I also know that the holes from the factory to install the factory wing I have will need to be filled in on the car! But I've seen this done to 91,92 firebirds before, and older models. But besides using a lot of 3M two sided tape along the glass, how do I properly install this WS6 wing to my 91 bird? Can someone help me?

 

PM Stephen or FYRCHKN, they will know.

 

Thanks for the info!
