I have a 71 351w, and i need water pump bolts without going to the junkyard. i'd rather go to a hardware store or home depot with the correct size because my car is at the transmission shop and i need em asap to move forward. any and all help would be appreciated

All WP bolts for a 302 are 5/16-18 pitch.... the length depends on where the bolt is placed.
