All the stuff I have seen on running larger TRE's has been based around using the GM ones and opening up the knuckles and pitman arm. But there may well be other options for 1 ton TRE's.
You many look at TRE's from the newer GM's after they went to independent front suspension as they seemed to get smaller. A good, though slow and hit or miss place to lookup stuff like this is Napaonline. I do a lot of research there. I type in a make model and year and then look up the part in question, they give relatively detailed specs on most parts. I then create a spreedsheet with the information on the parts I find. Sometimes I find something that will work right off, some times I never do. But I save the information anyway in case I change plans or others can use it. Unfortunately my TRE plans are based on the common GM TRE's so I have not looked further, so I can't help much in your search.
For what it is worth all TRE's I have heard of are tapered at 1.5" per foot.
I will start using Metric only when the duodecimal system is adopted!!
