Help needed with carb spacer/adapter

[Jerrys1stgJimmy]

I have an unused quadrajet and an old edelbroch intake and ordered an adapter along with my new engine from sdpc(scoggin dickey). When I receieved it I saw no instructions, just the spacer which made sense along with a bag of nuts and bolts. I have no clue what each are for exactly, and I cannot for the life of me figure out how to mount this. Does anyone have experience mounting a carb using one of these spacers could help me out on the hardware needed to make it work?

Thanks,
Jerry
