Is it normal or a convertible frame to flex a bit when jacked up?

First off, my car is a 1994 Mustang, so I imagine that they did not make frames as strong back then.

I had to jack the front end of the car up (I used jack stands to hold it into place). I placed the jack stands on the jack mounting points (as said in the manual).

Anyways, I noticed that the gap on the door got a little bit larger (about half an inch). It still opened and closed fine. When I put the car back down the door gap went back to normal, and it is a perfectly straight gap.

Thanks for your help.

Update:

I took another look at it, I may have over exaggerated a bit. It is more of a quarter of an inch. Like I said the doors open and close with no problem at all.

Update 2:

Thanks for the info. I was reading somewhere after I posted this that technically I should not even open and close my doors when it is on stands. Apparently with some peoples convertibles, they cannot even open the door or get it closed again when it is on stands.

Whenever I get tires changed I have always noticed that they will unlatch the roof when it goes up on the hoist. I now know why, so it does not potentially damage the roof.

    Convertibles are surprisingly flexable. They are built differently to combat the flex often coming with addition braces under car. You don't open doors on convertibles while jacked up or on hoist. Some cars the doors will not close until you set the car back on the ground. Drag race fox body mustangs are notorious for twisting body/frame. Subframe connectors are popular for performance use. Gaps change on some full frame cars when jacked up too, just not as much. We assume metal strong and stiff but it's surprisingly flexable.

    Well, your car is unibody... the body is the frame. If you are concerned, there are aftermarket subframe connectors that can be welded in to stiffen up your chassis.

    Better have the frame checked out. That's a lot of movement and the frame may be weak!
