I'd guess there aren't any interior panels on it, so you can also inspect the backside of the body panels for signs of repairs. Typical rust areas are bottoms of cowl, doors, cab corners, bottom of back panel. Also, how much hacking done on subrails (if they're still there). Likewise for the chop. If it's a hatchetly looking on the inside, expect lots of filler on the outside surface. One problem with the stock '35 front end is that it's a spring ahead of the axle configuration as opposed to the stock Model A being a spring over axle, and if it's got a suicide perch (or if you're switching to that style frame) that would be a spring behind axle.
