The frame is fairly easily shortened or stretched a little. There is a welded seam area just behind the kick down behind the front wheels where the frame levels off. I would recomend to get the body down over the frame and at the floor height you want, then install a front tire and hang a front fender to see how the wheel looks in the opening. Since the front wheel opening is tapered on the rear part but not the front part it is important to get the wheel opening in the right place at ride height with a tire size you will end up with. Saab stock tire may be too tall. I went with a 28 inch tall tire similar in size to a 235/75R15 that I used to run on my 58 daily driver back in the day.that part is up to you though. So far I am using the stock 17 inch wheels from the envoy with 235/60R17 tires. They may chamge to something custom when done but the offset and diameter will stay the same as the mock up wheels and tires.
