Walt,

Makes sense to me,  I'm going with Bob's reply to your question, heavy
duty apple rebuilds.

Steve,

If the tube shock bracket mounts the shock farther from the face of the
bracket, (away from the cars centerline) it will produce more bending
moment
on the bracket. (assuming the shock damping forces are the same, which I
doubt) The "force" on the bracket (shear) would be the same, but the
bending
forces (moment) would be higher. I don't know if this is true or not. I
don't remember anyone on the list having frame problems with this type of
conversions. I don't have one myself, but thinking about it.

question for Bob Lang,

Do you have to use the stock lever shocks in FP? If so, do you do anything
to them?

This may be a bit off, mostly because I really don't know but,

If you bolt the mounting for the tube shock to the existing bolt holes and
we assume that no other changes to the suspension are made.  How do you
"stress" the frame more?  The only way I can see this is if the shock has
way more "shock resistance" (stiffness??) than the stock (not hard i
guess).

In either case the force from the suspension is transferred to the frame
in a twisting motion.  Given the way that the conversions look (catalogue
pix) the thing I'd worry more about was flexing in the new tube support.

At any rate I'm looking at rear shocks also so any further info is greatly
appreciated

Thanks

My thinking is that the tube conversion may be stressing the frame; but
only
conjecture on my part.
But some other people who are more into performance are using levers with
the uprated MG shock valve.
