I’m putting in a turbo 400 in my 1968 cutlass conv. What cross member do I need and trans mount? A link to purchase the correct ones would be helpful, thanks

 

Use your current crossmember and trans mount. You will need to mod or change your drive shaft and yoke.

 

And e-brake cables to make it look factory.

 

You'll need to change the e-brake cables because the crossmember moves, not to "look factory". Since the e-brake cables hang off the crossmember, moving the crossmember back requires a shorter intermediate cable and a longer front cable. Note that the intermediate cable depends on the wheelbase in addition to the trans.

 

Thank you!
