you can get collapsible axle stands https://www.uktoolbo...CoaAu6PEALw_wcB but I can't see it really being necessary (or advisable) at the side of the road
if the car is of a certain age there's a pretty good chance your original jacking points in the sills are pretty rusty even if all looks ok from the outside
personally when mines done I will just get a generic scissor jack with a flat top and ideally a fixed on jack pad like this maybe https://www.zoro.co....QgaAsHKEALw_wcB (note I haven't checked max lift height on that make sure it goes high enough)
back end, jack using subframe rails / front end either using the bottom seam on the front edge of the bulkhead / flitch panel, or find a stable point on the front subframe but that's a bit awkward because of all the weird angular shapes
the main thing is as you're probably already aware don't use the floor pan or confuse the slinging brackets for jacking points which they defintely aren't
that's just my take on it anyway others may have better ideas
