none of mine were in great shape and id bet they have been recycled by now. i left them at my dads shop after removal.
you could remove the intercooler and put a section of hose/pipe in its place until a replacement is found or fabricated. thinking about it now, hindsight being 20/20 and all, i bet a good radiator shop could do a good job of replacing the seals and re-crimping the end tanks on a leaking one.
if you typically drive it for fuel economy rather than for performance, deleting the intercooler may not have a huge negative effect for you anyway. you can delete the intercooler permanently by routing the turbo right into the intake manifold through your choice of piping.
