Okay , the new improved thrust plate eliminates the need for the holy bolt or the dripper. Thanks for the enlightenment djwhog. As mentioned above it`s learning little things like that, that make FABO and it`s people #1.
You are welcome! I have even seen some with no bolt in the upper left on the same years that have the holley bolt.. Also there is another option that has a tang instead of a bolt too. Most of these are later model well if 75 up is late model right... 8)
Then in the race books they ecen plug the galley holes and run custom mods etc.
