Briggs 670cc Model or Dimensioned Drawings

[Topaz]

Quick favor to ask of you all:

In order from most-desirable to least, do any of you have any of the following for the horizontal-shaft Briggs 670cc airplane conversion(s):

1. A 3D model of a converted engine, with Ace Redrive, in a format that can be imported into OnShape.
2. A 3D model of an engine as converted, (minus all the stuff you remove for an aero conversion) in a format that can be imported into OnShape.
3. A dimensioned drawing of a converted engine with Ace Redrive.
4. A dimensioned drawing of an engine as converted, (minus all the stuff you remove for an aero conversion).
5. A proper dimensioned drawing of the engine as-sold by Briggs.

I've found some "kind of" examples of #5 online, but they're usually incompletely dimensioned, or actually not the right engine at all, despite being labeled as such. If dimensioned drawings are available on the Briggs & Stratton website, I've not been able to locate them.

Thanks in advance for any help!
