Parts counter guys hate to hear "I don't wanna pull it apart until I
have the parts for it can't you look it up in the computer??", when the
only way to find out what you have is to look at it :) (or perhaps
call a dealer with the VIN)
Other things are "can't you look up what size bolt that is??" heh
Some times with auto parts the only way to know, is to look.
Chevy Silverados come with two sizes of rear disc brakes. The
difference in diameter is only fractions of an inch, but are not
interchangeable. A GM tech who works at my local Chevy Stealership
informed me that the determining factor as to why one truck would come
with a certain size rear rotor vs the other size, was due to suppler
issues. Seems Chevy had to farm out the production to another supplier
in order to meet demand requirements. The result was two vendors sending
brakes to the assembly lines. Had nothing to do with GVWR or 4x4 or 4x2
drive train.
Disclaimer: this is what I was told by someone at a dealership - I seem
to recall we had someone who was a GM employee on the list at one time,
so if I've been informed incorrectly, feel free to enlighten me.
The point of that story was to illustrate that you can't try and figure
out certain things based on how the truck was built.
Over the years, GM C/K series trucks built from 88-00 came with tail
lights that used either 1157/1156 bayonet base bulbs - or 3157/3056
wedge base bulbs. Parts listings have both - no way to determine what
the truck has... GM phased out the 1157/1156 style circuit boards in
those trucks after a while... to use the wedge bulbs which are more the
standard these days... so they could have had trucks rolling off the
lines one after another with a mix of both styles...
Mid year production shifts make for a nightmare sometimes as well...
something titles 1996 might have parts on it listed for a 1997 or
1995... depending on what build date it has... Its not cut and dry dealings!
Ok I'm done...
