I got it from a Quebec guy I met at a United in Rockland ME 2 years ago in  
October
 
I'll try and dig out the data later

Dear Jim,
 
  I am interested obtaining in the lower fan shroud. Is it still  available?
 
thanks,

Hello,

Well after looking under the dash in the  usual place (and unusual ones as  
well), my trusty local garage  found the verdamnt  "I.S." where it was  
supposed to be, but  covered and obscured by a dealer-installed hazard  
warning 
flasher.  I forgot to look under it.....duh.  BTW, the Steve Laifman  seat  
removal pins have worked great.
Troubleshooting:  my IS-governed gauges gave  strange readings. The temp 
seemed to  run high (on a hot day over 250  indicated even with Derale fan 
and  fan shroud bottom extension from Canada).  Fuel gauge was funky,  
reading 
OK on the right or full end of the  gauge, but when it hit  about 2/5 full, 
it dropped to zero. My .IS,  under  test  yielded 5 Volts and was of the 
newer 
semi-conductor type. Got a new  one  from SS and it measured 10 Volts 
installed.  
With new IS installed I tested the temp gauge  this  weekend in full 
engine-running heat-soak. What had been 250 +  was reading 195.  With the 
electric fan running it goes even lower.  Gas hasn't gone down far  enough 
to 
report as of  yet.
Make note: if your fuel and especially temp  gauge  read where they 
shouldn't, check the Instrument Stabilizer  voltage!
BTW: I took the old IS apart and there are  only 3  electronic 
components inside: an NPN transistor labeled  FZT651 and two ancillary  
surface mount 
components that look like  either capacitors or resistors...that's  it.
One of the ancillary  components is dead (hence the half voltage).

Hope this is of  help to someone.......

Best regards,
Jim  Armstrong
