A little out of date, but....

If you bend a stock pitman arm, it'll lose radius.  That or you'll be
stretching the arm out.  I've heard the reason for the shorter radius on the
dropped arms is also because a dropped arm same length will contact the
springs itself, especially under compression...

And for a later post...  I seem to remember hearing that any welding to a
steering component is illegal.  I think I may have happened upon that in the
vehicle laws while doing a search on CDL rules and regulations (what was cdl
required and what wasn't).

Anyways, I'm slowly trying to catch up... usual disclaimers apply, not
positive about any of this...

I'm going to have a picture to show you guys hopefully tomorrow...
