Hello,  I'm rebuilding a 91 Turbo II for a Mustang II,
using the 91 turbo  The original rotor housings are
bad.  I have a good set of 88 turbo II housings to
replace the bad ones, but there are some differences. If someone can help me out please contact me at
jimcoffmanus@yahoo.com  Thanks Jim Coffman
