Spark plug thread repair.

Hello guys, I know this topic is not new on the forum but I have a question regarding the tools to be used to repair the thread.
My 2003 E39 blown out a plug which stripped the thread on the way out.
I went to AZ and bought a set of time insert with the correct spark plug size. However, I bumped into an unexpected issue: I can't find a socket small enough to go down the spark plug hole to perform the repair. The 16 mm socket used to replace the spark plugs for this particular vehicle is too small for the tool. When I tried an 18 mm it fits the thread maker but it can't go down the hole to cut the thread for it's too big.
Now, what are my options? Should I keep looking for a smaller socket or should I buy a smaller thread maker?
Someone advised me to remove the valve cover to get more room, but when I checked this morning the valve cover is not the problem because the socket goes past it and becomes blocked thereafter when the hole entrance shrinks.

Thanks!!

ok i'm gonna shoot this at you... maybe the answer maybe not
there are different 'thicknesses' in sockets...
search around for an 18mm that may be 'thin' vs the one you have now

i had a 21mm for my lugs that would not work... as in go down into the rim hole
went to home depot or was it lowes i forget now
but
i got a 21mm that was 'thin' vs the one i at first had...
worked like a champ

I performed the job with this custom made tool that I got welded together at a local muffler shop. Was super easy; took me 15 minutes to rethread the hole and place the insert.
Thanks for the input!

I went to both HD and Lowes to search for a thinner 18mm socket to no avail. So I cobbled up this tool. It cost me $5 to weld them together***128513;***128513;
