You used the word "restoration", if you are truly restoring the CJ2A, a
flat fender Willys enthusiast will spot Omix repros easily and make fun
of your baby. Better try a wanted ad on www.thecj2apage.com and browse
around while you are there, it is an excellent resource for CJ2A
related information.
On the other hand, if you are using the word "restoration" more
loosely, as in "fixin' it up to sell on Epay" then go for the Omix
stuff, the average rube won't know the difference.
