Well. You can buy a mount kit from hassport for our cars... I plan on dropping in a b18 gsr shortblock with a b16 DOHC V-TEC head in the future.... But check www.hassport.com .. They should have the correct mounts. Also, check out the post about the 84 civic sites. There was a whole bunch of links that I found an old thread about that you can check out. Welcome to the 1st Gen CRXers. :D
