I understand the 45 pistons ar concave as where the WD's are flat top. Other than that, is the height from wrist pin to top of piston the same?

JD Plowboy is correct. Remember that a WD 45 has a 1/2" longer stroke. Using the WD 45 pistons in a WD with the WD crankshaft will give poor performance because the compression ratio will be very low. Using WD pistons in a WD 45 engine will result in a very high compression ratio that I have been told requires premium gasoline and is appropriate only for short runs like in a tractor pull. Also makes it hard to start with a 6 volt system.
