69 barracuda dash to firewall bolts
I also bought a set of front and rear clips from Jim at DMT, his looked a lot more like the oem's that I removed from my 68. If I remember right there were instructions with the front because like you said the 7 green ones ( more square ) only go on the very bottom, dead center and then 3 outward from center each way for a total of 7 and all the smaller ones are along the top, sides, and the very first clip on the bottom on each side. Also the bottom clips do not always come green in color like the picture you have above from DMT, you can see that mine were black. I bought some clips off of eBay and they did not look anything like the ones that I bought from Jim. I have not installed my windshield yet so I really don't know how good they are going to work, but like I said they look a lot closer to the original oem clips so I am not expecting any problems. By the way you get only what you need, there are no extras.
