66.58 percentile in MHTCET means you can accept a rank in the range of 50000 to 60000. Now this is not your actual rank rather it is assumption based on MHTCET Percentile vs rank statistics.
Now if we go through last year's cutoffs, then you can expect civil Engineering in

• MH Saboo Siddik College of Engineering
• Terna Public Charitable Trust's Terna Engineering College
• AP Shah Institute of Technology
• Sanjivani College of Engineering
• Imperial College of Engineering and Research

etc. But keep in mind that these are based on last year's data and this year the cutoffs can change. To get complete list of all colleges you can get based on your rank use this link http://www.careers360.com/mht-cet-college-predictor
