businesses there will cut the decal to a specific size. So if you find an ebay business selling the correct logo, check their sizes and send them a message to request the exact size you need if it's not listed. I've used several caliper decals from ebay vendors with no issues over many years and miles of use and abuse. Drop them onto a clean surface and they'll stay there til you remove them.
