when I put the SS spoiler on my GP I put a tape on the trunk where I wanted the spoiler to sit and then just measured where to drill the holes. Or you can take a piece of carboard, mount the spoiler on that and then use the carboard to lay out the hole pattern on the trunk lid.

The following is something I copied from one of the forums way back in 2006. I wish I could give credit to who wrote it but I'm sorry I didn't note it.....
I'm also sorry I can't verify whether the measures are accurate....



Anyway, I got some dimensions that can help, I think.

trunk edge to outside edge of spoiler mount base riser/spacer (measured at mid-point lengthwise from front to back of the spacer) is
8-13/16".

trunk front lip to leading front edge of spoiler mount riser straight back is 26-7/16"

Spoiler mount base risers are 3/8" tall. This puts the front of the spoiler 1-3/4" tall on the leading edge of the spoiler. It's 2-5/8" in the back. Difference is due to the slope of the trunklid.

Tip downturns have a running gap of 1" from the body panels the along entire length front to back.

Ok, NOW you can go drill your holes!
