I got the trans installed today (from the bottom) and it ended up that having the Dirty Dingo slide mounts worked out pretty good as I needed a little more clearance in the bellhousing area so I just slid the engine forward about an inch and gained all the room I needed............I also took the stock crossmember and bolted it up to the trans ......Cool.....Just need to drill some new holes in the frame when it hits the sweet spot....LOL......although we are pretty close right now.......I also have plenty of room with the 4L70E trans to shim the trans mount to get the correct drivetrain angle later..........Too Cool!!!........Time for a Nap!!!
