Tom,
My,my. Good luck today with the "modifications" and customizing!
I sure hope some professional Jag rear end type guys jump in here. I have seen three failures like this on the Jag rear ends;
Run N Gun-weld let go
Dhris Knueven - Blue and White Unique broke a lower arm at last years Fling.
And now yours.
I, in a very non-professional Jag expert, have to agree with Bill. Looks like fatigue to me?
Can they be built with stronger tubes? Maybe a "double-wall" prior to welding the caps on?
I think Bob (Putman) makes his own tubes?
DV II's use a single wishbone setup, totally custom made for our horse power and torque, but I'd still sleep better with a "Double Wishbone" set up.
DV..Here's to a very quick recovery fella!
EDIT..PS, just went back and read all of the original thread. Some good stuff there From David!
