1970 Front End vs. 1971/72 Conversion
 

Hello, I was hoping some of the more experienced members may be able to help me out a bit. I am looking for a 71/72 cutlass fastback. I prefer the more Square grill on the front end vs. the more rectangular wide grills on the 70 cutlass. I was wondering what would be required to put 71/72 grills on a 70 cutlass. Are the fenders the same? Rad support? Hood It/headlight bezels/etc?

I only ask because I have found a 70 cutlass that is in great shape and at a fair price and would like to buy it and hopefully swap the grill or whatever other parts required to make the conversion. If anyone has any details, it would be truly appreciated!
