Selected User Reviews For Holley 21-3 LS Accessory Drive Bracket Kit
This perfectly fits the holley brackets for maximum accessory spacing flexibility to match the LS engine platform's crank pulley. It's perfect for my LM7 5, which is mostly stock. 3L V8.
So my husband needed this for his truck, so I went ahead and ordered it for him. He was excited when I handed him the box, and when he saw what it was, he was relieved because it was the last thing he needed to finish up his '88 GMC pick up. However, the part had a couple of large scratches on it, which he didn't mind. The only thing he was upset about was that he didn't receive a HOLLEY sticker for his truck.
This was a perfect fit and was very simple to put together.
I did some research on the brackets and found them on Amazon for a reasonable price. Holley makes quality products, and these brackets are an excellent example.
