The viper t56 into fox mustangs was popular for a while before the magnum came out. I have a viper t56 in my mustang . I cant help you with a swap into an early mustang but if you need any information i should be able to help.a viper case needs a specific bellhousing. Quicktime might make one for a coyote. I had an issue with both stiffler and aje crossmembers which are meant for t56 touching the transmission case. If i put spacers in the transmission ended up touching the tunnel. I ended up using a american powertrain x factor crossmember. I would suggest trying different crossmembers out and modifying the one that will give you the best fit.
