a warm welcome to the forum, & good luck with your build.
donors do come up now & again, just keep your eyes & ears open for them.
the steering racks & drag links etc etc are available very easily at fairly good prices from Rally design,
stick with this forum & you,ll learn where to find most bits needed for your build.
suggest you put your location in your profile as there maybe a builder close to you who could help in some way.
all the best
andy
