There is no fender tag, Mexico didn't use them.
I am not sure what rear end was used in Mexico but it can't be a 7 1/4 with the 270 HP the engine makes.
I am waiting for a picture of the engine from the front to get to me.
It does have front disc brakes.
I will post the picture as soon as I have it. The car is not where I am at the moment.
