Re: 97 4cyl TJ Wrangler
 

It's a waste of time in my opinion. You want to step back and think of
easier ways to do this. Taking over an abandoned project you find in the
newspaper is one. You could probably find one for ten cents on the dollar.
If you like fabricating parts and can do it well, then maybe this isn't such
a bad idea. But if you were like that, you would already have your own
custom off road vehicle business and more orders than you could possibly
handle.
