Thanks for the kudos!

I have a set of the 68-72 C10 towers, but they are pretty close to the same as the 305E towers. You need to find towers out of a 63-66 C10. If you look on your front cross member, there are two sets of holes. The front set is where the 305 towers were mounted and closer to the cab, you will find another set. The 63-66 towers are longer and shorter. It is my understanding that the 350 is a taller motor than the 305E so it needs to sit lower for hood clearance. Someone please correct me if I am wrong. The tower bolt holes on the frame share one hole and you can see the difference in length of the two towers in the bolt hole in the cross member.
