You ordered a kit for your car that does fit. You had an incompetent mechanic working on your car.
The mechanic or person installing your coilovers made a huge issue out of bolts not fitting into the lower mounts that bolt to your car. We ordered OEM bolts from Subaru for the same year car. The bolts went right into the mount holes with no issues. The holes were tight due to power coating thickness. We emailed you the photos showing that we installed bolts into the coilover mounts with no issues we did not even have to tap them in with any tools. Simply pushed them in by hand. Who ever you had installing your kit did not try at all and cost you a lot of time and hassle. They also raised an issue with the top bolt being a camber bolt and no longer working, but did not understand that the camber is adjusted through the camber plates. I highly recommend finding another person to install any parts on your car who knows about the parts.
We emailed you photos 8 days ago and you have yet to respond. You have also contacted us from various emails under different names. We replied to the original email sent with photos and measurements and replied back with photos we took showing the parts do fit and work.
