Charlies is what I got, bolt and nut- I haven't a clue, but I see someone else posted it. If you need to use stock manifolds I will give them boat anchors to ya, they are from a truck so clearence would not be an issue. Everything is looking good.
Thanks 5.7, but I do have the stock car manifolds that came with the motor. Right now my only concern is the steering linkage, not sure if either manifold will allow adequate clearance for the shaft. Maybe I'll do steer by wire!
