Thinking about speed tech 3 link rear modified for A body

Was thinking Caltrac rear suspention but now thinking about a Speed tech 3 link rear suspention. Car will do mostly road duty but also a little track duty, road and drag. Car is mini tubbed 69 Barracuda. Old drag car that I would like to turn into a pro-touring car eventually. Best thing is I know one of the guys at speed tech and have seen the product and It is top notch.
Caltrac is more of a drag setup. I think the 3 link will fit well with my subframe connectors. What do you guys think?

Thanks
