What year is this beauty ? From what I can see it is a modified VAC. The steering arm and linkage on a VAI is parallel to the ground. The grill on a VAI goes all the way to the bolster, not like the narrow front VAC. I will try to post a couple pictures of my 1950 VAI for you to compare with. Also the shift pattern is different on the VAI.
I am no means a Case expert, but from what I see and have read about the VAI, yours is a owner modified VAC.
