(You can make a simple plate that fastens to the valve cover bolt that will slip over the dipstick to support or hold it in place.)
If you have a look at other AMC vehicles there should already be one I have four AMC engines and they all have them they are a standard item on matadors. I posted a pic of one so one would know what to look for.
