Just wondering if anyknows if the front valliance and bumper from a 79 will fit on a 74?

 

Not easily. The fenders would need to be changed to the 78-81 design and you would need different brackets in front of the radiator. The radiator support is slightly different so I don't know if you would need to change that out also.

 

I was wanting to put the 70-73 front and rear ends on mine... But decided I liked it the way it is.
