Yes, I did forget to mention that. One important thing about the
tube shock conversion I must mention, is that all of these
conversions, if not properly maintained have a SERIOUS SAFETY
PROBLEM!!!!
Please if you have a tube shock conversion make sure the bolts
holding the front brackets on are properly torqued down and check
them regularly. If these bolts become loose, they are apt to
shear off, with potentially serious results. (Bad ASCII ART to
follow)

If the bolts are loose the large bending moment caused by the shock
causes the bracket to twist and imparts a shearing force on the
long bolts, and can cause them to shear. This is not a problem if
the bolts are tight, so no need to be concerned as long as you
maintain your car and check the bolts once in a while. If you
put the conversion on years ago and haven't touched it since it
might be worth 5 mins just to check and make sure the bolts are
still tight.
