Rear Spoiler

[AJ4U2]

I got a question if someone can help me out and at my age i can use some help, I got this 1992 SVX LS-L at least that is what i have been told, but it did not come with the rear spoiler on, I just bought a stock one and wanted to know what the size of the holes are, I know about the dimples, but the bolts are are bigger at the spoiler mount then the threads are so do i just make the top big and the inside dimples small for the screws, I have seen a lot of talk on the transmission with this vehicle, i got about 70,000 on it now now and have not had any problems but the only filter i know to be change is the internal one, I don't drive it hard but i do get with the program on the highway,Sorry about the lenth of the post, if you don't ask you never know,
Thanks
