Trying to determine stock or not

This is my first experience with CJ's so please forgive these silly questions.

Can 31's fit on a stock 79 CJ5 ? Reason I ask is my wifes 5 came with 31's and has a nice stance. But its a bit too tall for her to get in. If they are not stock I may search out some stock springs. Probably one of the few that would want to actually lower a jeep R)

Another reason for lowering is we may slightly downsize the tires to a 30X9.5o The brakes in it are non power and it really sucks. Figured less tire weight should increase stopping power. Here is a pic http://www.earlycj5.com/forums/attachment.php?attachmentid=17959&d=1179880950 Thanks

Yes, 31s would be fine with factory springs, as would the 30s.

You have drums all around? I thought that disks were standard by '79. You should be able to find all the parts you need to convert to power brakes.

 

Sorry forgot to mention its front disc and rear drums.

 

Any thoughts of adding a pair of factory entry steps?

 

or a set of Carr side steps like my Jeep has.
