I will scratch out our old measurements (there was a thread on this a month or so ago too). But we went to the aft raked rig at the same time. Plus because the tramp lifts up under the load, you need to mount the loops well forward of where you would normally have the slides.
We put a lot of reinforcing underneath the tramp (some dacron and tramp mesh layers) too - I would not recommend going to eyelets without adding some serious reinforcing, even if you are going to tie back to the sliders.
On our Marstrom, we used one piece of 6mm spectra for each side, threaded through all 6 eyelets with big knots at the ends. Worked fine. If the sliders can run far enough forward, that would be a good option.
