Special pains had to be taken when drilling out the rivets so that metal filings didn't remain in speaker. I used two small magnets (one on inside and one on outside). How were the two stainless screws installed??

What? Did you forget? :D

Easy peasy. I've had to get screws in difficult places before. In the case of your speaker I probably would use a bit of wire or string and a tiny drop of superglue.

Great idea using the magnets! Simple and safe too!

I've been doing the super glue and tape trick to help mount screws and nuts for a while.

Thanks Again for the advice.....Tony

I think he drilled two holes to form a "keyhole" in the speaker basket, so he could push the head of the screws through the frame, then the transformer bracket holds them in the harrow end of the slot.

Long needle nose pliers to grab the threads close to the screw head.

I don't see anything that difficult there.

After you get the hole drilled then: There are some good ideas from members.
AS wiscojim stated.
1. Get A pair of forceps (long variety) or long nose pliers to get the screw between the cone and basket. (very difficult but maybe you will luck out.)
2. Fish the some sewing thread, first through the hole after getting something heavy that will be small enough to slide through the hole. either glue or tie the weight with the thread, then insert into the hole from the outside of the cone basket, then release the other end of the thread while holding the basket on a vertical position, allowing gravity to pull the object out of the frame.

Note: as a matter of choice, You could put star washers first on each screw before you start the process. Gluing them next to the head to keep them in place. That way as you tighten the nut and washer on the transformer the head won't spin when tightening the nuts. in the process.

3. You can then then wind the thread around the bottom of the screw after removing the weight. Make sure the thread is not sitting next to the head of the screw. (all sort of complications if you do that).

4. Glue the thread or tie a knot to the bottom of the screw. Eventually by maneuvering the basket into a position where you can manipulate the screw up though the hole, tying the other end of the string to anyplace that's available to hold the string taught. Once you get the screws through the hole, Glue the screw around the hole filling up the hole with glue of course.

5. Let it setup, then put the transformer carefully over and down on the screws so as to avoid pushing the screws back out of the basket holes. Then put your star lock-washers on (better electrical contact and bonding) or use captivated nuts , as They have attached star washers Then your nuts and tighten carefully. Tighten till snug then a little extra slight twist.

Here's another Idea. Not practical but it can be done.
Drill your holes large enough to allow the screws (or bolt) head to pass through.
then with a Dremel cut a slot next to the hole that will allow the screw shaft to slide into the slot, then finish by glue and such to complete the installation.

I got this Idea from installing toilets. They use a bolt that has the head shaved ground off to form a bar. ( ==O== ) From the side view it looks like a T, then insert the head into the metal bracket slot previously screwed to the floor. Then turn the bolt 90 degrees. Align the toilet base holes over the now positioned bolts. Put on the washers and nuts and tighten. Then they have a cap that covers the bolt and nut.
This picture should help.

More than one way to skin a cat.
