Just installed tti headers !
Here's pictures of my installation. Also we had the front of the car up on car ramps. That helped a lot with manuverablity, checking clearances, putting the trans in, putting the X-pipe in, etc etc.
these are 1 3/4" stepped headers. I helps to have 3 friends helping too.
The one pictures show the driver side mount lifted, but it's only for the install. The very next pictures shows the mount settled back in it's stock location.
