IMO, the minute washer faces on these 7/16" Cragar SS lugs working against the Cragar supplied washers are too small to be reliable for holding torque. Doesn't take much to start digging into the washers. Couple that with any wear on the studs over the years you may be constantly re-torquing...
I believe OP was interested in what components are involved, not where to obtain them. Evidently Dale's does not by a search I tried.
From the '69 OM..........

There are several pictures in the forum that show the stiffener in various orientation. If it's solid, it's good IMO.
That said............ I did find this picture a couple minutes ago................

I like the MP suggestion of the bell crank being "straight across in any view".
I'd relocate as necessary.
