I used these letters : https://www.aliexpress.com/item/32827718301.html?spm=a2g0s.9042311.0.0.1d884c4dcurCfa The original Hyundia "electric" decal isn't much more expensive though : https://www.hyundaipartsdeal.com/genuine/hyundai-emblem-electric~86312-k4000.html Removing the old badge is easy - get about 5 strands of fishing-line twisted together like a rope, and use this to saw behind the badge. To get the alignment and spacing right, I used a card frame with clear sticky tape to place the letters from behind and check that it looked straight, and some squared graph paper as a guide grid.
