A RG550 question

[deoreo]

I'm looking for these neck dimensions:
Width at nut 43mm
Width at last fret 58mm
Thickness at 1st fret 17mm
Thickness at 12th fret 19mm
Radius 430mm

I know the current RG8470F J Custom has these specs, but I really prefer the look of the RG550 (maple neck w/dots, pickguard..etc..)

So the question is, of the early RG550's are there any years I should avoid?
ie: were those dimensions only for the 80's models? What about the 90's DX models, or the later 98-2000 models?

I know the 20th reissue has these dimensions, but I'd like to know the option for earlier, used ones.

I don't think there are any 550's you need to avoid, they're all great. The Wizard neck was the same dimensions until Ibanez switched to the newer "Prestige" Wizard.
