NA to Turbo manifold

have been trying to find a driverside turbo manifold for a while but to no avail. I have an 85 z31 that has been sitting for almost 5 months, my question is does anyone have a spare manifold i can buy (reasonably) OR does anyone have experience with a custom made manifold and is either willing to make me one or show me how to make one? I'm fairly inclined but always trying to learn. I just want to drive my lawn ornament… Thank you for your time guys.
