Use the simplest keywords you can think of: 1974 blazer dimensions,
for instance, to find pages with the size of your Blazer, or cheyenne
package to find pages with a description of that trim package.
If you don't get matches, try reducing the number of keywords, or widen
your search. Rather than specifically looking for 1974 Blazer dimensions, try
just 197 blazer dimension.
The search engine is very literal, so don't try Boolean stuff like "and"
or "or", or symbols like "+" or "*". It will order results by number of
matches, most relevant on top.
