You should post some photos of the bolt and where it is. Perhaps seeing it will bring forth some ideas on how it can get done or maybe someone with the same vehicle might have already had to cut one of those off.

"Dremel" have bigger/thicker/both cutoff wheels then many see in tool or bit kits. (Typically 15/16" diam 0.025 or 0.04 "Heavy Duty" disks.)
But Bigger wheels, 1.25-1.5", often "eat" small Dremel models and other "knockoffs." Output shaft and bearing(s) in them are weak.
B&D make/made one w/ better locking to change bits but single nose bearing is weak and die soon cutting even w/ small disks. I have several actual dremel die same way.
Dremel et al makes Diamond and other coated wheels but they won't last long cutting large Class 10.9 or SAE Grade 8 or harder.
Think ~ $10 for "supersaw" style Carbide is expensive?
HD wants $26.97 for One Cubic Boron Nitride coated "High Performance Metal Cutting Wheel"

They make/made Saber/Jig Saw Carbide blades but these likely too short to reach most CA bolts and sleeve. Can't get them @ many stores or only rated for Ceramic Tile and related.
Problem w/ Carbide and others the bushing sleeve is soft and can "plug" the coating trying to cut the bolt in it. Sim problems to cutting/grinding in Aluminum...

"2) the area in which the car sits - not an option" cancel that option in most cases.
Even sawing/grinding can start a fire but often not as easy w/ torches or cause other legal problems in a lot of places just having disable car for hours or days parked outside.
Example: My parts car must be on pavement and covered to keep code enforcement not bothering me. Other have "show cars" etc covered if they can't/won't drive them every few days for same reason.[This message has been edited by theogre (edited 11-24-2022).]

yeah, but - "2) the area in which the car sits - not an option"
Also, my storage area for new tools is overflowing for now.

I dismissed a rotary tool because I was under the impression that any disc wouldn't have what it takes to cut through a bolt like this.
air die grinder OTOH...maybe. I'd have to have a very steady hand (which I don't) but I may be able to steady my hand with a support from below. I'll look into die grinder cut off wheels now. If they're made of the same material as the discs I got from Harbor Freight - well, those discs cut through a grade 10 bolt with great ease, recentty.

"Dremel" can cut Class 10.9 but eats a lot of abrasive disks.
"Standard" and "Heavy Duty" 15/16" diam break easy too w/ HD break a little less.
reinforce disks can break too.
Dremel quick system disks can break too but bit harder because wide area the arbor grabs.
If can find small washers for screw in arbors to sandwich the disks can help for same reason.
Easy breaking is Why I grab most disks at flea markets etc.
To save the tool, use minimum force to cut or grind anything. And variable speed tools are better.
