Thanks for the info - Kohler is now off my list of suppliers for anything. Never thought much of their designs anyway.
HD has them - part # 83978 (trust me it took me two trips and me digging around in the speciality drawers) - still figuring out this works but looks good. I also saw a blog that if you complain to Kohler enough they will send you the repair kit for free.
I found this posting concerning the same issue.How to repair/replace a Kohler seat that has the anchor bolts
If you have a Kohler toilet that requires the Kohler seat anchor kit 84999, here is an inexpensive alternative
Step 1
If you have one of the Kohlers with the Kohler anchor bolts holding the seat, do not buy the $46 anchor bolt kit 84999.
Step 2
Instead, remove the old anchors and bolts which have an aluminum end which the stainless bolt screws into and over time become corroded together. Use a 1/8" drill and drill around the bolt removing the anchor material until the bolt can be pulled out.
Step 3
Carefully clean the hole with a 11/32" drill to remove all the remaining anchor material.
Step 4
Then go to your local hardware store and buy a 10-32 3/8"x3/4" rubber expansion plug (check to be certain the threaded part is brass and it has a shoulder on one end), a 10-32x1.5" Phillips bolt and a couple of small fender washers to fit the seat. Total cost under $4.00 for two.
5.
Step 5
Assemble being careful to not tighten too much and crack the porcelain.
hope this helps. remember be careful not to chip the porcelain
Replacement of Seat on Kohler one piece toilets: Applies to toilets with NO access to the underside for nut application
1. Don't bother calling Kohler 2. Don't buy the 84999 replacement expansion bolt set from Kohler ($47 + shipping) 3. Get the appropriate replacement seat from a supplier (I went to Lowes) 4. Remove the stainless bolt and aluminum anchor from the existing seat and toilet. The anchor is a soft metal which expands when tightened ("molly bolt"). This is the only hard part. You may have to use a Dremel tool with a reinforced abrasive disc to cut the bolt head off, or you may choose to use a hacksaw. I grasped the screw head with a pair of pointed vice grips and turned and pulled (after loosening them a bit with a screwdriver, so I could get ahold of them) until the aluminum expansion bolt broke off from the inside. If you saw off the head of the bolt, you'll have to drill the hole out to 11/32", the original size of the hole in the toilet. 5. Go to a hardware store and get the following: Two 14x1" or 14x1 1/4" stainless metal screws with pan head. Two large Pop-toggle screw anchors (or other nylon anchors of your choice that can fit tightly in a 11/32" or 3/8" hole). Two stainless (or nylon) washers appropriate to the size of your size 14 screws. Ace hardware had these in KC. Tap the pop-toggle anchors gently in the holes in the toilet until flush. Place the seat replacement on the toilet over the anchors. Place the washers over the holes in the seat, put the screws through the washers and the new seat, in the anchors. Tighten with a screwdriver and you are done. Total cost around $1.50, but the best part is that you can now replace the seat without removing the metal anchors if you wish, and the anchor is nice and tight.
Then go to your local hardware store and buy a 10-32 3/8"x3/4" rubber expansion plug (check to be certain the threaded part is brass and it has a shoulder on one end)
What about these?

It looks like something that might work. Although I can't seem to find the actual specs on the pieces.
Hi, I just wanted to post my experience with this fiasco:Replacing the toilet seat - another method
Thanks to everyone posting on this forum. Here were my steps:
Removing the Old Seat
- Tools to remove the bolt head: Dremel tool, extra cutting blades. I used a model 200 Dremel tool and "420" cutoff wheels.
- Tools to remove the bolt and mounting hw: Electric drill, 3/8" hole saw. I happened to have the hole saw from a different job. View attachment 20723 Eleven bucks for the set
- Tear off the old seat, use the dremel tool and blades to cut away the plastic, including the plastic under the bolt head. The washer should spin/move freely. This goes through the blades pretty quickly; a different type of blade might be better.
- Use the blade to cut off the head of the bolt. Use light pressure and high speed. After the bolt head flies off, do NOT pick it up right away. It is HOT.
- It will now look like this:
- View attachment 20724
- Use a small screwdriver or knife or whatever to chip away the grunge, now like:
- View attachment 20725
- The magic step. Use the hole drill, and in 30 seconds you will be through the mounting stuff; the bolt etc. will have fallen inside, and the hole will be clean:

Mounting the New Seat
- Parts needed (I used what I could find at Home Depot): Triple Grip Anchor, Cobra 173s. 2 Stainless steel pan head (look at the picture, the head is flat on the bottom) sheet metal screws, #12 x 2". Pack of stainless steel washers, 1/4". I was paranoid about corrosion so I got stainless. View attachment 20727
- Gently tap in the anchors. They will just barely fit.
- Put on the seat
- Put a washer on each screw, put in the anchor, and tighten
