Ive got a 98 4-door 2wd Blazer, with a rear drop tailgate and the rear window that goes up with 2 lift supports , what is the correct part number for thease lifts ? where can I get the right part ?? I put some Monroe #901167 on about a year ago , now my window doesn't seal or line up with the roof line . any suggestions for a fix ? Thanks , also whats the part # for the drop tailgate lifts ?
