What's the better lower stress bar?

[sfwilliams@comcast.net (Scott F. Williams)]

Damnit, that actually makes sense. :^) I think I've been stood corrected.
Anyway, like I said, an ME-type could shed more light on this subject. Ha!
Anyway, I still contend that the factory/TT bar will do a better job
stiffening in that ONE plane. I has to... I mean... things are tied
together... and stuff. (To put it in my own technical vernacular.)

;^)

Anyway, I'll be getting back to the Memorial Day fiesta now...
