OOOoooo..

it would help if had known that’s what you meant (me bad)..
First you will need the FLM 10600 trany adapter on the transmission and review your placement options. Two options are available (front or rear), I chose the rear so wouldn’t encroach on the front servo plate.
Then you should run a screw on both side of the transmission through the frame rails. These screw will work on the back front hole. (IE) the transmission holes are (4) total on each side and they are broken up in sets of two with the divider in the middle so the only original screw hole that will work in the back set / front hole.
Then you will need to enlarge two of the existing holes per chasis rail, I ran mine in rear back and front back holes. The front / front hole doesn’t work with the transmission adapter on each side of the frame rails, I found that the dermal works best for this. (you do know that you can only use a total of (6) screws?)
GO SLOW and for god sakes man!!

don’t drink or (whatever) before attempting this rail fabrication!! But one you successfully completed this fabrication then by all means feel free to indulge in the finest brain cell killers money (and the law “wink, wink” will allow..
You will also need buy longer transmission screws and washers for them… the screw size is 20-25mmL (I think??) your call..
That about it (simple haaaa)
Hope that helps??
Have a great one..
