Clammy, Ive been afraid of that.
If the bracket has spread apart, I would suggest that you squeeze the bracket back, and then JB Weld the carriage bolt to it. Don't use a lot, and try to keep it off the top, where the bolt sits in the bracket, as it will interfere with the console tunnel that the bolt goes through.

Cheers!

ok, me and my Dremel Multi-Max, after a couple of drill bits, got the cap of the pseudo nut off. Now there is a sleeve, about 3/4", on the business end of the carriage bolt. I need to take the tripmeter reset off. Then I believe the dash will slide off and I'm hoping to grab both ends and crank them apart, the bolt and nut sleeve that is.

so, unfortunately you are right Clammy. I finally got the 'nut' cut off and sure 'nough, it's the bracket on the tank that has rounded out, not spread.



any suggestions for this fix?

Really hard to "see" the entire situation and dimensions with the picture:
Is that harley part number 5419 for carriage bolt?
Is that carriage bolt a 5/16-18?
Would a U-Nut work in this application...placement of u-nut in slot...
But turning a correct size bolt to a stud to replace carriage bolt, and placement of red threadlocker on stud that threads u-nut
or
Would a WELL NUT work in this application...placement of well nut in slot...
But turning any correct size bolt to a stud to replace carriage bolt, and placement of red threadlocker on stud that threads the well-nut.
A well nut will probably required shaving of some rubber to create a grove on the sides in order to let it slide into the slot.

never thought of those. I think a U-Nut would be better. Here are a couple of pics that might help with the "seeing the whole picture and dimensions." The area/receiver used to be 5/16" square to hold the square neck of the carriage bolt, but now it is a rounded 3/8", so the bolt just spins. Here are the pics.






Let me know what you all think. Anyone.

Much easier to see with the provided information.
The mounting point on gas tank looks like a rectangle hollow raised area.
That rectangle raised area looks about 1 3/4 inches by 3 1/2.
Can you cut a piece of flat thin metal that would slide into that area?
Like a metal ruler.
After fitment is determined then remove the piece of metal ruler.
Then use your dremel tool to cut a a slot into the metal ruler the size of carriage nut square.You want it tight.
Slide cut metal rectangle piece (ruler) into place from right to left or left to right under that raised area.
Remember it now has a slot.
Now: Think for a moment...stick piece welded to gas tank in picture looks like it is suppose to push carriage bolt head UP.
So you might need to pull UP in it to bend it into place. It looks bent down.
Maybe use a string to pull it up(fishing line?)
So that stick thing is now sitting in the groove you created.
Then you slide your newly purchased carriage bolt into original slot while applying a little down pressure to push stick thing down and at same time sliding into slot created by new metal rectangle metal ruler piece..
You are basically duplicating the slot but under the slot with the metal ruler.
Then place a small o-ring or 2 on top side of carriage bolt slot area to keep it in position for console. Basically to help keep carriage bolt square in the newly created groove.

I looked around my garage to see what kind of flat metal that was pretty strong and lo and behold, there was a metal ruler.
Here is the final product.




thank you im, never would've thought of it myself. It's an exact fit

You are welcome.
Looks good.
That should work in theory.
Let us know if theory matched reality.
