i installed my windshield myself in my 92 ram 50. cut lut the old glass with an oscillating saw cleaned off the old rubber as best i could. bought 2 tubes of adhesive at my local parts store. used a standard caulking gun to apply a bead around the edge and set the glass. that was 2 years ago no leaks no problems. the only thing i should have done differently was replaced the retainer clips for the windshield trim.
