I would agree as to the strength and durability of the epxy/m.b. combo and you are correct on the torq links for visual purposes only...alignment is maintained by a grub screw and slot.

Aluminum seems a good grade and from first test on the oddball-out third strut in one of the three-fer packages the type aluminum used appears strong yet ductile and doesn't chrystalize and become brittle under moderate heat(750-950f)

Anyway here's a great photo resource link that I just stumbled across last night.
