I think the best fit for ALL of the boats is a single 1 1/4 inch (maximum diameter) sheeve and cheek plate with becket on the sliding car, and a fiddle with the larger sheeve being no more than 1 1/4 inch in diameter on the fixed car. Height of either car with sheeves and plate has got to be no more than 1 1/8 inch above the track, and preferably a drop less. Your boat and Dan's probably have the same layout and I guess that your track was installed a drop more inboard than his. Mine is different and most of the proposed solutions would fit.
Putting a fiddle on the slider would call for one sheeve with a wider diameter and we don't it there considering the limited space. The fixed car has no bearings and is closer to the track. I really think the 3 to 1 purchase is satisfactory for our boats. I've moved the pin locked car under load (15 knots of wind) with no lines and no mechanical advantage and it's got to be less than 100 pounds of force to slide the car (not to hold the sheet). 3 to 1 would cut that down by a factor of 3.
I'll call Garhauer on Monday and see what they can do. I'll also fax them the drawing you had on a previous post to represent the "worst" case, along with photos so they can see what we're talking about.
