I have a GXP diffuser on the way and need to figure out how to fix a few attachment issues. Since i bought my car 2 years ago, my stock GT diffuser is not attached at 2 points, since at some point in its previous life, they were broken.

Any way i can fix this?

I've got the same issue. My plan is to "try" and repair the area with a plastic welder and some broken plastic pieces I have laying around my garage. If that don't work, I guess I can always drill another hole and zip tie it.

Well, there are 3 things you can do.

Search eBay for junk yard listings for that part. You'll find them. It probably wouldn't be expensive, and they'll sell them when they're untouched. That is option 1.

Option 2 is to cut the busted plastic off, and bolt a metal L-Bracket that fits in the spot to the vertical tab. Use a bolt that is large enough to secure the part, but small enough that the hole you drill doesn't compromise the plastic. Then use another bolt to connect the diffuser.

Option 3 is the aforementioned zip-tie....

For option 1, what part are you referring to? As far as i know, the spare wheel tub is bonded to the metal and isn't really removable.

Yeah, I'd drill 2 small holes on each piece if there is enough space not too close to the existing holes and use 2 zip ties on each and cinch them down and cut the tails off. That way, it could easily be removed if need be.

92253748 is the GM repair kit part number for those.

You can make a stud by cutting off the head off of a screw/bolt's . J.B. weld that in what's left on the car, and bolt it on.

How does that work? Any pictures?
The pieces in that kit are bonded into place with adhesive. No pictures since I have never needed to use them. I just knew the kit existed and wanted to let the OP know that there is an "official" fix for this.

GM Parts Direct shows the drawings (which others probably do too)... That should be sufficient to see how they'd go over the existing tab.

Nice find. :) Pricey, but it is what it is.

Yeah, super pricey. Over $100 for a little thin bracket? Drill a hole and zip tie it, man.

I bet I could draw up some simple plans and have someone make a big load of them for half the price for each one, probably a lot less.

Why draw up plans when you already can find simple drawings? And why have someone else fab it when you could easily do it yourself for free??? :D :D :D

Just sayin......

This info is from ALLDATA:

Bulletin No.: 11-08-62-001

Date: May 03, 2011

Subject: Information on Wheel Well Repair Kit

Models:
2006-2011 Chevrolet Caprice (including PPV), Lumina (VE/WM Models)
2008-2010 Pontiac G8

A service kit has been released that allows the repair of the rear fascia to wheel well lower mounting points on all VE/WM variants as shown below.

The fixing points may break due to impact damage and as the spare wheel tub is made from a fibre reinforced material, they are unable to be reliably repaired with plastic welding or other methods.

The kit, Part No. 92253748, includes three metal brackets, which can be affixed to provide a renewed mounting point. Refer to the image below. The kit also contains detailed fitting instructions.

I don't have means to accurately cut metal. Do you? I mean, I have tin snips. Maybe that would work for what is needed.

Normally, I'd fab something up if I could. It depends on how it needs to fit. It does depend on what tools you have, though....

For something like this, there's bound to be a solution at the local hardware store. Thing is, it would be unofficial and unsanctioned by GM..
