For Sale is one NOS Genuine GM Small Block Starter Brace. Back in the day when most people changed their starters they would toss this brace away. With the torque of these small blocks the starter tends to flex and can cause the teeth on the flywheel to go bad. This brace bolts from the block to the front of the starter to help stop the flex. GM makes at least two different small block starter braces to help you figure out if this one is for you see picture with measurement and as close as I can measure as the crow flies center to center 4 1/8". I know the other one measures approx 5" from slot to hole. You will ever receive a brace in a bag like the one pictured, or possibly one in the box. The ebay fitment guide is only a guide so please make sure this is what you need. With all the motor swaps going on it's definitely better to measure and be sure this is the one you need, as I do not want anybody to be unhappy, so please make sure before bidding. When only GM works this is for you! Thank You for looking, and good luck!
