Just got a 1988 converible w/ a richmond gear 6 speed.
Got a few questions:
1.  What is recommended for cleaning the rear plastic window.  Don't want to
scratch it and need to clean some spots where it was setting under a tree.
2.  Horn not working - any idea where the horn relay is located.  I have
checked the fuse and it is fine.
3.  On the digital display for the mpg the top right part of the last digit
is not working.  in other words a 1 would only have the bottom segment
light.  Also the mpg does not light up.  the L/100 when in metric works but
not the mpg.  Any ideas on fixing or does the whole pannel have to be
replaced.
4.  Throttle is sticking a little.  I have sprayed lithium grease on the
linkage where it attaches to the throttle plate but it is still sticking.
Any ideas on where it would be.  If you tap the throttle pedel it will fall
back.
5.  The speedo is not right.  It is off by a 10th of a mile for every mile.
In other words you get .9 for every mile on the odometer and you get 64 on
the speedo for 70.4 on the gps.  Any ideas on how to change/get the computer
reprogrammed or calibrate the speed sensor.

Thanks,
Tony
