I am thinking of going with detroit speeds subframe. What would the stock frame go for? It has all the components, comes with a fast ratio steering box. It has disk brakes and is in good working condition. Shocks are a little worn but i have brand new adjustable shocks and an aftermarket sway bar.

with disc brakes i'd say around 4-500. Subframe alone is prolly worth 150 so whatever the brakes are worth?

I'd be very interested in that

I would too, im in the middle of changing my front subframe.

bare subframes are 150-400 depending on if the mounts need work and how bad they are rust pitted.
