Grill mount holes

The holes in the core support for the gtrill are large rectangle holes with no access through the bottom of the core support. What fasteners go in there?? The LMC catalog and my shop manual show some sort of female fastener in there but no detail or description.

i don't have a picture, but they were a type of capture nut. i'm thinking they were welded or something because once they break the only way i have found is to drill holes through the bottom of the core support to allow access for the new nuts.

Yes, cage nuts went in there. You can also find them and replace them if you want to go that route.

but how so you get them back in the holes? i don't remember there being any easy access to those?

You put your core support in the clothes dryer for 45 minutes so it gets turned inside out like your socks and t-shirts magically do.

OT, but;
If I did that, i'd lose half of everything I own.

She's pretty easy to get along with, but I've learned several things through the years:
Don't paint in the attached garage, don't bake powder-coated items in the kitchen, and don't leave foreign items in the clothes dryer

plus the old holes are oversize now!, I went the larger holes under the core support!

The bloody things are a nightmare to get to as it is. At least this way you can get a socket or something on to it.

It looked like they were tacked into my support. I knocked out the couple that were left and drilled down thru the core support and used longer bolts with fender washers, locks and nuts. This way the top and bottom of fastener is easy to access.

That's what I will do. Thanks guys.

Ed.
I used a long drill bit to make a pilot hole on the bottom of the core support and then a hole saw for access to the hole in the top for a regular bolt, nut and washer. The hole in the bottom works as a drain to keep the support from rusting out like the originals did.

Definately a pain to get out, a hole saw from the bottom is the way I've done it as well. The nuts that are in there are a form of Tinneman(sp)nut that is use all thru our trucks. It's basically a nut that is attached to a U shaped piece of spring steel that holds the nut in place to quicken/ease the production line. Similar pieces are available at your local ACE hardware, just remember they 5/16 fine thread. I did mine this summer and they worked just fine and you don't have to be a contortionist to put it back together.

I found some small rectangular nut plates that are normally riveted into place. Ground them down to the right size and welded them flush into place. Worked perfectly.
