I wanna drag race----help

Any idea if the driveshaft is the same for a 4 speed or automatic? My car didn't come with one(must have been optional) and I need to find one anyhow. How fast would I have to go before I need subframe connectors?
Would I need super stock springs to run in the 12's.
I know,I know.... too many questions !!!!!

I would install the subframe connectors. I assume your going to be side stepping the clutch at 4500-6500 RPm ? Yes I say you need the SS springs. Becides have you ever heard a racer say " I'm going way to fast, I need a smaller engine?" If you run 12's you'll want to run 11"s etc.
