I have been searching far and wide, and I cannot find what I am looking for. I am trying to find solid information on the different specs between the pre-89 MKIII subframe and post-89...I am trying to build engine mounts for my 1UZFE to fit in my 91 Supra MKIII, I have found lots of information for pre-89 mounts, but not for my 91. If anyone can help me out, please let me know. Thanks guys.
