Ummm.... Unfortunately I don't yet have my T-Bird to 'play-around' with!
I was thinking that I would need to make an adapter - but I feel sure it wouldn't be too hard to knock-together?!?
Go for it Rob - and keep me informed - Twin headlamps is what I'll be doing with mine once it's here!
<edit>

Here is a photo I took when orientating myself for this project!
The stock T-Bird lamp is fitted in the center of the lower yoke.
I don't have a picture of the Rocket II fittings - but I'll get onto it!
