"The second pic shows the bolts used to collapse the springs. We used 5/8-8
acme-threaded rod 93410A620 ($30) and welded on nuts 94815A011 (@$3) from McMaster
Carr, if memory serves. They are 7 1/2" long (threaded section only). I cut HMWP
washers (in white) so they spin easily, below standard 5/8" washers.
The bolts go through nuts on the arms, as I'll show later. The arm nuts are
93023A662 (@$20). The forged arms are probably the most critical parts, and must be
made of tool-grade steel. I don't know the exact spec. Hopefully someone with more
knowledge of metals will chime in with a suggestion."

"This next photo shows the arms which the threaded bolts screw into. Dim's are about
1 1/8" x 5/16" on the nut end, and it tapers towards the hooks. Again, these must
be made of some very strong steel. The dimensions allow the hooks to engage an
unsprung spring, as well as collapse it sufficiently to install on the truck. There
is a minimum spring length to pay attention to when collapsing, as you don't want to
collapse it too far and damage the spring. I don't recall the min. length, but it's
in one of the manuals."
From the bottom of the nut to the inside of the hook is 10 1/2".
