Technical Removeable Top hold downs

I am starting to make a top similar to this 'Carson' Style:

For those of you that have removeable tops, how are you securing it to the body?

First thought I had was using rivet nuts on the body where I would add some mounting tabs to the frame of the top. Figured someone on here would have some recommendations. Pictures would be great.

 

When I installed a Carson styled top on a 1939 Ford convertible I used ready available thumb screws for the windshield attachment points but tried several things to hold the rear of the top in place, I finally ended up using two seat belt latches, just mash the ****on to release. HRP

 

I took a set of head rest receivers out of an old set of seats and welded them into the tops of the quarters on my roadster. I then cut the posts off the headrest and welded tabs onto the top of them. I can now fasten the top to them when I have it on the car or remove the tabs so they are not sticking up where I would whack my elbow when cruising with the top off. The front just clamps to the windshield posts in the normal way. Takes all of 2 minutes to remove the top. Stole the idea off someone here.

 

Take a look at those chrome "frankenstein" bolts on a Miata.

 

Years back when I had a 37 cabriolet with a carson top it was fastened using these:

C1 Corvettes use latch fasteners on the front of their removable hardtops as well.
