And don't depend on the BIG box stores like Auto Zone, Advance, O'Rileys...all they know is how to look up something in a computer, most are as stupid as elephant dung about engines.
Make car
year car
model
engine in car 4, 6, 8
automatic/standard
2 wheel or 4 wheel one keyboard stroke at a time. If it wasn't on a computer they would be lost.
I grew up before computers and we looked it up in a catalog. Most mom and pop stores knew something about vehicles back then.
Catch my drift
