### ⭐⭐⭐⭐ Review
*by C***S on 1 March 2024*

ICT Billet makes nice parts and stand behind their high quality parts. However, I was very shocked when it didn’t include the alternator bracket or anything other than the bracket that adds the additional support hole on iron block 5.3. For the price the drill bit and tap should be included. Luckily I had already bought the alternator bracket and ordered the bit & tap when I ordered this bracket. Worked perfect but the price seems ridiculously high.
