I'd say mounting the jack pads with bolts visible from the side is your choice, however there is a very interesting picture on page 19 of The Shelby American number 35 (1981) taken by the author of the article in 1966 while on tour of the Shelby facility. The picture is of the driver's side profile of a 427 Comp car or S/C still in the raw without paint or side pipes yet, still sitting on slave wheels. Also the very front of another Cobra in similar condition is in part of the picture just behind the subject car. Both cars have their jack pads mounted and it clearly shows the front ones are mounted with the bolts visible from the side and the rear are the opposite. I wasn't there so I'm not sure who mounted what and how, but there is at least one example captured in that fashion in 1966. This same picture may answer a few other questions for originality buffs.
