*idea* short metal cv joints

[T_Tank]

After warping snapping an shearing u-joints in my unimog an my reworked Big Earl monster truck I'm wishing lego or somebody would make a cv joint that would be the same dimensions of the 3L u-joint that would be a lot stronger even been tempted to find a machine shop an see what it cost to have some machined from alum or even steel since its really the biggest issue i have with making a strong pendular suspension system. Big earl's issue is there isn't room for a reduction at the hubs due to the steering parts i've used to reduce the offset from center while using power puller wheels an the unimog I need something more then 8t to 24t in the portals (my mog an crawl agressively over 5" ledges but ends up blasting a u-joint quickly.

Anyways Ideas comments concerns opinions?

There is a metallic CV-joint to be used with flatted shafts.

I've seen these before but it would appear the ones sold there are to large to fit inside the lego "torque tubes"
