Not sure if yours has that tiny ledge on the upper rad support facing the radiator like a 67 up does so you can tape a level across. Put the stands as far forward on the rails (I put em between the lower rad support, and the K frame) and as far back on the rear rails (i put em just forward of the shackles) as you can so the car doesnt try to droop on the ends. Check your door gaps and make sure the doors open and close well. As long as its level, the gaps are good and they open and close well, then crawl under it and weld em in. Nothing will change from that point on. If it was goodly before, it will be goodly after
