This is an example of a tall side cover 216, correct?

this is the 235 shorter side cover:

Wonderful! Now I'll be able to tell for sure if it's got a 216 or 235.

Next question: Is there any way to tell externally, a high pressure from a low pressure 235, aside from the engine serial number?

Thanks to all - hope someday this helps otters.
