This hardware kit is for mounting the 'Round' transmission mount A15/05.  You'll receive the mounting bolts, nuts and washers required to not only 'mount your mount' but also those required for the Interceptor's removable trans mount's mount or crossmember.  Make sense? Not for the Mk1.  Mk1s don't have a removable crossmember.  Those Mk1s are just so special! And all Grade 8 - We love grade 8!
