TRD Style Spoiler, Instructions? Options

[Hazmat]

Ok so I have a kinda dumb question here but I recently picked up a TRD Spoiler for my 94 Hatch from eBay. Heres the link for it:

So my question is it didn't come with instructions or anything on how to install it but it did come with hardware but I've been looking at the places where its going to mount and I'm kinda worried at looking the bolts that are holding the stock spoiler on now as they seem bigger than the bolts supplied for the TRD Spoiler. Does anyone have any experience with this style of spoiler? I may just have the body shop install it for me hoping that they know how to do it correctly so I don't screw it up myself

sorry to dissapoint, but that is not a TRD spoiler.
trd "style"... meaning, it looks somthing like a trd spoiler, but not really. the posts are way exaggerated, and its also higher.

Hmm well I just remembered but forgot to add that it's more of a Hiro spoiler isn't it? But I'm still trying to find some sort of detailed write up on possible self installation
