SteeringColumns

[gehl@domain.elided]

I have a couple of steering column items, sorry if this is a repeat.  
I have several columns to choose from, most are nontilt variety.  Has 
anyone else noted two different steering shafts used, as in, the 
wheel nut threads are different.  3 of 4 shafts have a larger thread 
size with coarser tpi.  I have standardized on the larger style, it 
is generally from a later model as best I can tell, probably best 
design.  All shafts have collapsible plastic center section.  While 
my columns show no signs of impact damage, a couple were short by at 
most one inch.  I gently pressed all to a standardized full length.  
It does wonders for getting the column attachments bolts to align.  
Question.  Was it a mistake to press back the plastic center section? 
There appears to be no visible harm and this section is a stout as 
ever.  Also, I am not able to get the steering wheel column switches 
to come within contact of their cancelling lobe.  It appears to not 
fit totally together, yet it looks and functions great in all other 
aspects.  The horn contactor barely meets.  If anyone has been here 
and can shed light, I appreciate your comments.  Mark
