Hi
The angled adapter was for use with FastATA/Indivision/Lyra - sorry misread your original post :O
This will not fit with the Mediator LT4- I just measured the angle and it is far too steep. However we could probably put together a flat version design for you which will be a squeeze. One further problem I think will you will encounter is the 40-pin cables connected into the FastATA will push up on the underside of the Mediator (especially if they are fitted with relief strains). There maybe some lower profile 40-pin connectors.
