Bf-109G-10 to K-4... How to?...

I have the 1/48 Bf-109G-10 from Revell of Germany… The kit has a serious lack of detail, specially the cockpit, so I decided to detail it, and as I have to detail it, why not to make it like a Bf-109K-4’s cockpit?.. the panel lines in the fuselage are not a problem, the problem is the cockpit… I’ve checked 109lair.com, but they don’t have pics or drawings of the K series cockpit… So that’s it, I need good photos, drawings… You know, something for make a good scratchbuild of the cockpit… Another thing: Surely I’ll need replacement decals (I think I’ll pick some from Eaglecal Decals… any recommendations?)… Just curiosity… are the K-4 stencils the same that G-10’s? Thanks in advance. Regards.
