65 cuda 273 upper starter bolt

Real easy on a slant, not so on a small-block. I would be tempted to install a Magnum starter since 1/2 size & weight, and did in my 65 Dart 273. If you are ever stuck on the roadside trying to swap an OE starter, you will see. You must get the steering in just the right place to be able to work that heavy beast past the Pitman arm and exhaust.
