saw online today a 89 jeep wrangler, 5 speed, 2.5 engine, runs good, decent shape the only thing wrong it has a bad frame, like it won't pass inspection they want 500 for it, now just a question, how hard would it be to find a frame, what years would work, or even where can I find a frame, or where can I find this info out? and do you even think it would be worth my time to switch everything over to a new frame

You'll spend all summer and way more money than you think working on this.

And I'd wonder how you could damage a frame that badly and not hurt anything else.

Maybe buy this and then find another with a bad engine? That wouldn't be a hard swap.
