My 89 Iroc a few years ago:
1) No sir! A bungee cord is not just as good as a tranny mount.
2) No Sir! Orange extention cord does not make a good wiring harness for your headlights.
3) No Sir! White tub chalk does not make good T tops seals.
4) No Sir! An old gym sock does not work just as good as a airfilter on the TPI.
But, What do you want for 500 bucks.
