Ok time for an update.
The tube supplier has been pretty slow but hopefully I should have it this week.
Finally took a closer look at the ute setup today.
To attach the kits to the utes you will have to drill out the inner front spring mount hole, in the chassis rail, to accept a 12mm bolt. The stud on the utes has a step down from 12mm to 10mm at the chassis rail, there is no way around this unfortunately. If you were to remove the traction rods at a later stage you would just replace the bolt with a 12mm 90mm long grade 8 bolt so no real big issue.
Attached are a couple of photos of how it will sit on the ute.

This pic shows the step down in the stud, the chassis rail will need to be drilled out to 12mm to accept a 12mm bolt right through. The stud is easily tapped out of the outer mount.
This pic shows the plate and bush mounted on the plate, note that the two outer bolts stop the plate from turning hence the change required in the design of the triangular plates.
Showing the triangular plate and bush on the outside of an original coupe/sedan/120y front spring hanger, it would be possible to do this will normal eyed springs (Reverse eyed springs will not work this way).
Another angle showing the above setup.
New coupe/sedan/120y hanger, triangular plate plus bush sandwiched next to the original spring hanger.
After some searching I have sourced some rod ends with a 3/4 UNF with a 5/8 rod eye, these are Teflon lined at a reasonable price. So am looking at going back to a 3/4 UNF L/R thread in each end of the rod (No plug reducing to 1/2 UNF thread).
Will keep you posted when the next round of parts arrives.
