Leaaking hardtop on 1992 500 SL
 

I recently purchased a '92 500 SL with only 40,000 miles. Car is in beautiful condition except hardtop is leaking on both driver's side and passenger side. Water seems to be coming in from upper front corner of window. Does anyone one if seals in this area can be replaced and if it's a job that's easily done? Thanks in advance.
