Is this more to help hold it in place or because its a difficult install??? ive never done one before done carpet, seat covers, etc..never a headliner though...in other words would someone like my 11 year old son or wife be a ok helper...meaning they wound t have to do much but help not much mechanically??
and another question do I just need the headliner or so I need sail panels also?? Im seeing/getting mixed responses if I just need the 1 piece ABS headliner or the 1 piece ABS headliner+ sail panels...???
