Opinions on purchase?

I say cut out the entire bottom of the car and put a full chassis under it. You can go with a four link on the rear and struts on the front with a rack and pinion. If you can do the welding yourself the cost won't be too bad. A fair amount of work but the car will be much stronger and far better for racing. I have a 65 barracuda that I'm cosidering doing the same thing to, it is a parts car otherwise. My other 65 will be a street car.
