Prevent your case from coming apart due to the original screws not tightening after opening gearbox. This will result in stripping of the gears. 

You may notice the plastic on some of your original screws after removal and then they will not retighten. This is a sure sign that the GB screw hole is stripped and the screws have lost their bite. 

We have done all the hard work and spent a lot of money in research for you and these parts that I am now selling are the best and will be the right type of upgrade that will give you the best benefits.
