JZ to 350Z G35 Crossmember Installation Instructions

G35/350Z Transmission Crossmember
This is a basic guide that will help get this crossmember in the vehicle smoothly with minimal downtime. Please read all of the instructions before trying to install this crossmember as it will not fit if attempted before completing the instructions. This mount is CNC bent on a precise press-brake and check afterwards on a jig for fitment to make sure everything fits before leaving our facility. Again, please read all of the instructions below before attempting install.
-Now that you have your 350Z/370Z/VQ transmission attached to whichever engine you have selected and placed onto the engine subframe, the transmission should be dangling in the tunnel area.
-Use a jack to lift up the center portion of the transmission, just in front of where the stock 350Z transmission mount bolts onto. You want to keep the transmission mount area clear so that you can bolt the new transmission mount and crossmember into place while the jack is still supporting the transmission from beneath.
-Remove the factory 350Z/370Z/VQ transmission mount that may still be bolted onto the transmission. If your transmission did not come with one, disregard this step.
-Unbolt the Collins Performance Technologies transmission mount from the new crossmember and bolt ONLY the mount to the 350Z/370Z/VQ transmission using the (2) M10x1.5 30mm hex flanged head cap screws including in your bolt pack.
-Once you have the mount bolted to the transmission, very loosely place the Collins 350Z/G35 crossmember onto the mount using the hex head cap screws and washers you just used to get the mount off.
-Very loosely (2-3 threads max) put the (4) hex head cap screws through the crossmember slots and into the chassis.
-Once every fastener is properly threaded in, it is now safe to tighten all of the fasteners to proper factory spec.
