Boiler front compatability

[Lehigh Valley Lines]

I have a 4-4-2 Lionel that came from a PA Flyer set a few years back. I was wondering if I could swap the boiler front from an aftermarket part from a PW K4 Pacific 675, 2025, 2035 or a Turbine 671, 681, 2020? 

Does anyone know if they aftermarket boiler fronts are compatable with any different locos, especially the 1645 4-4-2 that I own.

Thanks.

Hi!   I recently purchased a 'repo' boiler front on E-Bay for my 2035.  Knowing your engine's number is helpful as the listings often show which front would work.  All the best.
