I don't have the Weistec adapters myself, but I think the answer is no. Weistec list that they use M10 bolts, whereas the Mars adapters use M8. Weistec doesn't list their center to center bolt spacing either.
The mounting plates I made are about $135 total for four plates as is (0.250" thick...
Finally got around to designing some mounting brackets to utilize the Mars Accessory Adapters to mount the topper and get them fabricated. Absolutely rock solid. A bit tricky to install with the storage boxes since you can't easily see the adapters to align the bolts, but with enough patience I...

I used this post as guidance. I was able to do it without having to remove the rear seats, but it made it a little more challenging. But still way less effort overall.
@Autofitpro Are you able to provide installation instructions for the mounting straps by chance? The included instruction booklet didn't have any of those details in it.
Definitely need to remove the topper. The wires come up directly underneath the gear tunnel door release buttons. Maybe there's a way you could remove all the bed panels and go in the side, but I think the wire comes up between body panels, so that might be a lot of work for no results.
I procrastinated my install for a while but finally got it more or less finished. A couple of notes:
I ordered storage boxes for both sides. There were no instructions included for assembly of the storage boxes, but more importantly, there are also no mounting holes in the topper itself. I had...
Just received my delivery today! For those wondering about timelines for fulfillment, here is what I experienced:

Is there a way I can confirm if I made it into that batch? And I presume mid-September ETA means initial arrival into the US. If so, what's the estimated time frame for actually receiving orders? Thanks!
They're a lot cheaper than the $100 per piece Weistec adapters! And feel free to give the shaft collars a shot and let us know if you find something that fits well. I already have the Mars adapters in hand so that ship has sailed for me, but I don't regret it. They're a perfect fit and high quality.
No worries, approximate is totally fine for now! Just wanted to start perusing potential candidates for mounting. :)
Also, I know there has been a lot of discussion about the Weistec adapters. @krockett posted a link to the Mars Accessory Port Adapter which, for about $120 for four of them...
Just placed my pre-order! Wondering if anyone has done anything like a MOLLE panel on the inside of the storage boxes to keep things in place, or has any other good ideas. Also, if it's possible to get the dimensions of the storage box, that would be greatly appreciated!
