Need riser bolts! Please someone help!!!

A general rule of thumb is to have the screw go into the material at least 1 diameter of the screw. So if you have an 8mm screw, you should have at least 8mm of thread in the base.
I would screw the screw in as far as possible without the risers in place. If nothing else you can verify the shank of the bolt isn't too long. Is the threaded hole drilled through the base plate/top of triple tree?
I'm loving this exchange everyone, thanks for all the input.
So with the photos David provided we see that the riser is closer to 25mm than the 32mm I was working with from the website I referenced for GenMar risers (again, it's easier to make the bolts shorter than to make them longer!).
Unless I'm mistaken the only part the bolts thread into is the handle spacer. Fortunately, my MCL risers displace that part so I had it in my box of take-off parts to assist in fettling the bolts. The thickness of that part where those bolts thread into the spacer is 11.25mm. The shank of the bolt just passes through those holes in the spacer and doesn't engage their threads.
Here are photos of "The Shortening"
I inserted the bolts until their threads bottomed against the handle spacer then backed off 3/4 turn. The black is Sharpie ink from where I marked the edge where it protrudes from the bottom of the spacer so I knew where I had to cut.
Dremel! My first and probably still my favorite power tool.
I used double nuts to act as a cutting guide and to protect the threads from an errant spinning disc.
After dressing the ends I threaded the shortened bolts into the spacer until they bottomed out and checked clearance on the underside.
That large hole on the left is where the long 'special bolt', item 20 in msg #18 in this thread, passes through the spacer. As long as the tips of the bolts are not proud of the flange around that hole they should never come in contact with the top surface of the upper triple clamp.
Here you can see a ~0.3 to 0.5mm gap with a straight edge positioned across those flanges. The tips of the bolts should never contact the triple clamp.
With a single washer in place, nominally 1.6mm thick, the length of the bolt is 45mm (you'd want one washer at minimum since this is not a flanged bolt like the OEM). So two additional washers - total of 3 - should ensure the bolt is properly clamping the bars and riser to the spacer and not bottoming out in the spacer. The decorative cover retained by those M4 screws would then be ~3mm higher than if proper OEM bolts were used.
So there ya go David!
Best of all, I just happen to have a personal courier that will be traveling back from my hometown to David's at the end of this week so the shipping is free!

UPDATE. I got some time to finally install these risers with the custom bolts made by STrider. They worked perfectly. Thank you so much. I have no doubts about the strength of the bolt. Here are some pics. Thanks again to all of you and this forum. By the way, the risers make riding so much more comfortable!

Awesome to see you finally were able to get them installed. I really enjoyed the opportunity to help and the challenge that accompanied it! It was fun.
Do did you need to use more than one washer? They look great in place.
Ride in good health and comfort!

Did 43mm's end up to be the correct length?
I’m not sure the length. They were the shorter bolts that STrider made me. Seems like plenty of thread contact was made with 2 washers added.
I just want to chime in and thank all the participants on this thread.
A. for clearly identifying the problem
B. for working through the details of the solution and posting detail in the steps
C. Posting supporting pictures
D. The OP sharing the details and pictures of the final repair to the problem.
FWIW, I believe that this is what one would call an ideal thread, at least to read and gain knowledge. Not difficult to do, just a little follow up on everyone’s part. This thread makes this site BETTER!
All too often we are left hanging on details, pictures and/or final outcome.
Good job participants!

41.8mm according to the math listed in the below.
Is there supposed to be photos in post #43?
I don't see any.
Yes, many photos.
Seems some members' devices fail to display them from my posts. I see them on all of my devices, of which there are many. The browser on my TV even - one of the lousiest browser on the planet.
¯\_(ツ)_/¯

I don't even get that much.
I just see big blank spaces between the paragraphs. I tried it on three different devices, four different browsers, same on all of them.

I only get the missing image icon with the question mark in Safari, but it's an old version in an old OS.
Are you using newer Apple kit? Is the image format HEIF? That's the default for images but they can be exported as .jpg or .png.
