a few pulleys the fan and a few other parts up in the front
The basic chassis parts will be the same, or at least workable, engine parts like pulleys may not work for you. The easiest way to check is by going to http://www.autozone.com/
and looking at the part numbers for the parts you want between the two different models. If the pulley (for example) on one is a different part number than the pulley listed for the other one then its a good bet the parts are different. Just a 1/4" difference in the diameter of a pulley may not even be noticeable by eye, but can make a significant difference on actual design purpose.
