Works great. ### ⭐⭐⭐⭐⭐ Great *by V***A on August 28, 2024* Perfect fit ### ⭐⭐⭐⭐ Great quality but for the price should include more *by C***S on March 1, 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. ## Frequently Bought Together - ICT Billet LS Truck Iron Block Interior Third (3rd) Hole Bracket Low Mount Accessory Missing Casting Boss Alternator Fuel Pump Compatible with Silverado LM7 LQ4 L59 LQ9 LMG L96 LC8 551921-LS01 - ICT Billet LS Truck/SUV Iron Block Drill Template to Mount Alternator LS1 LSX LM7 LR4 LQ4 L92 L96 Bare Aluminum Designed & Manufactured in the USA 551445 - Drill America 1/4"-20 Tap and #7 Drill Bit Kit, POU Series --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/502227297-ls-truck-iron-block-interior-third-3rd-hole-bracket-low](https://www.desertcart.co.th/products/502227297-ls-truck-iron-block-interior-third-3rd-hole-bracket-low) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
