I got a 99 DX without cruise, is there any aftermarket or oem cruise control systems thats recommended will work

 

Do you have a junkyard with lots of 96-2000 Civics in it? If so, one can get OEM cruise control parts there and install CC using guides such as:

There are aftermarket systems available, too. Google.
