I think after assembly, heat treatment would make the rods stronger. But, I think a 1.25" .213 wall will be stronger than the 1.25" .120 wall they offer. If I went up to the 1.75" I would still sleeve something (don't know what would fit in there?
I still may get a Spidertrax tie rod to see how it does!
I used FKB-HRSMX12T 7/8" -14 high misalignment heims from Polyperformance
Same tubes for the tie rod and I got those at Aircraft Spruce in Corona, CA
