I spent some time on Artec site looking at trusses. I have a front D44 from a (I think) late 70's Ford that I want to put under my XJ. Tubes are 2 3/4" dia and 1/2" thick. I do not think I need a full truss for 32" tires but I need a one stop idiot proof complete set of brackets for it.
Artec's stuff look good and have great reviews but come with a hefty price.
I used their truss on my 14 and their shock towers on my struts . I would have used them on my front 60 but it already had a brake bent link bridge welded into the diff housing and couple other things that would have required cutting an artec up to fit , so I just made what I needed from 6x3 .250 rec tube capped with 3/8ths cold rolled and addes sone internal gussets ... cost $25 , but took me my weekend to fit up and finish ...lol...if my axle was stripped down it would be a no brainer to buy an artec and just add some extra to it as it would speed up my time to being on trail again...lol... like before my new treps dry rot from age .
