Support for ICT lower alternator mount - Camaro style
Used this as the 3rd support for my Low Mount alternator on an LQ4. Works great.

Great quality but for the price should include more
ICT Billet makes nice parts and stand behind their high quality parts. However, I was very shocked when it didnโt 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.
