I'm fitting the hood on my '53 AD. It seems like the more I raise the radiator support the better it fits. I'm up to about 1 1/4" between the support mounts and the crossmember. I've got good measurements on my cab mounts, as per the assembly manual. I can build a spacer for the rad support gap, thats no problem. Anybody (or everybody) go this high? Any other tricks?
