1 to 10 rating on the install of Vintage Air on a non-a/c 70 Camaro

[SS1156]

I am looking at a really nice clean 70 Camaro that is an original non-a/c car from the factory and I was wondering on a scale of 1 to 10 (10 being the hardest) how hard the install is? I am very mechanically inclined but I was just wondering how the fit & finish is and all that good stuff? I will be changing out the top pad so I can install the correct center vent. I want it to look right. I'm also wondering if there's a kit to move the a/c compressor over to the right side of the motor? I can't spend a fortune on one of those billet front drive systems right now. I might be able to do that later, but I'm just trying to do this on a tight budget. Thanks guys.
