Just FYI...

Having chatted with Dub and looked at the cross member again...

....I do believe I am going to cut Toms "H" brackets down leaving
a 1/2 - 3/4 inch "stub" where he had the bolt holes for the c/member
on the lower legs of the "H"

It will essentially leave a saddle bracket with stubs.

I will weld the Calmini c/member to these stubs ( extra surface area)..

...and that will secure it solidly, AND tuck it up a bit higher for clearance.

It will still be removable with 4 bolts as before.

Any comments and / or derision ( ) glady accepted!
