Kayline soft top

[4runnersr5]

I just bought a super clean 87 4Runner and have decided to buy a soft top for it.I have tracked one down for 300.00 I'm not to sure what it all comes with yet but I have just recently started researching it and I'm finding you have to drill a bunch of holes.Im just wondering if anyone know's what it really takes for it to be done right and pretty much how it all goes together.

Thank you
