Ok I have done the search but my questions were not clearly answered.

Has anyone made a blue print or seen one of the Granada adaptor plates? I know you are going to say they are $20 ea so don't waist your time but  I am in college becoming a Trades and technology teacher and I have full access to a Plasma CNC machine, CNC Lathe, and CNC Mill as well as tig welders and so on, so why not? I could make 20 sets in the time some one could fab two. Does any one know the years and Models I can find the GM metric callipers on?

Also a 75 Granada showed up at my local Pick N Pull today with a 5 bolt rear end under it. I have read that It is a bolt in, I have also read that I have to move the perches, and I have also read that it is both narrower as well as wider by one inch. What is the low down on this fitting since there is mixed answers?

Any other parts worth while on the Granada? I am pulling the rotors since I have access to a brake lathe so why not!

yeah sorry

The GM metric calipers are 78-88 according to Speedway, I was looking at them last night. I'd also like to get some measurements of the adapter plates, it'd save me about $60 if I just made them myself.

I'd go with the new calipers instead of pulling them, better off with the peace of mind that way.
