Edelbrock 2691 TQ adaptor?

I was wondering if anyone had one of the Edelbrock 2691 adaptors, if so here are a few questions.

The adaptor looks like it bolts down to the intake using the outside holes and the inner holes are used for mounting the Thermoquad.

My main question is, do the studs for the TQ thread into the adaptor, or is it like the other adaptors that use a captive bolt from underneath. The other possible way is that the TQ studs would pass through the adaptor and use a manifolds inner pattern holes.

I will be using this on my Ramcharger and my intake only has the wide format holes, no inner pattern. This is why I am asking the questions.

I've looked at a ton of pictures and can't tell.

Thanks,
