I used paper and a pencil to create a template for the mounting holes for the 89+ 3 piece spoiler. I figured the community could use the template so before I sold the templates, I scanned them into my home scanner and included a marking showing the scale in inches and mm's. They are in PDF format. I tried printing out a couple of them and they are clear but the sizing scale is too small. Maybe if someone knows how to fix the scale so it prints out properly, we can update the template. I think Photoshop prints to scale, so maybe that's the way to do it? Here's the link for the file. Right click it and choose "save target as" to save it to your hard drive. http://www.echowavepro.com/supraphotos/89+SpoilerTemplates.zip
If this template can be made to print out in the actual scale size, it should offer very accurate locations of the mounting holes in relation to the body, with the exception of the front side spoiler tips since they are over 13" from the other holes, they would no fit on standard paper.
