Hello, if you are looking for a little more modern ride, here are a couple of ways.  #1 You could adapt/purchase a rack and pinion set up, coil overs etc.  Or #2. if you are handy and on a budget you could consider "clipping" the front frame section. You may already know what this means. I think the 79 Cutlass, Malibu etc are good donors and have an acceptable width. Keep in mind if you do decide to pick up a junker for the frame clip you can also use the diff and brake system. Any replacement parts for the donor car can be bought at any NAPA store. This isn't that complicated but you will have to adapt/make a rad support, front bumper brackets and so on.  Like I stated, if you're handy and on a budget "clipping" is not a bad option. Just my two cents worth!!  Good luck.
