Use of GM Transmissions require modifications to transmission tunnel!
No fabrication is required for the install and all of the structure under the dash can be retained. The dash does not need to be removed. The trans tunnel requires hammering in the transition area where the tunnel area meets the bellhousing area and where the bellhousing area meets the firewall. Additionally, the trans tunnel will need hammering along the sides around the bottom for clearing the sides of the trans pan.
