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

just bolt it on man its not that hard....take your plastic off your hatch from the inside...you'll see a couple bolts on each side...take them out...line up your new spoiler and bolt it back on....if it makes you feel better and your stock bolts are bigger then the ones that came with the wing then use the stock ones...it wont hurt anything
