Re: 4l80e swap?
my stock X-member is used along with no drilling on frame. I did use the 4l80 trans mount b/c it is slightly offset and works better.
You will need a trans controller, and it's $$.
I am using an Abbot Cable X unit to run my stock speedo from the PCM. (I can ship those for $300)
I have a low hump cab and plenty of room.
