Good luck getting a trans jack to work easily on that.

I like how I made my frame mounts that have a piece of 1.75" tube ran through them parallel and up inside the frame. I ran all of my electrical and fuel through those.

There should be some pics in my build thread. Making a good full skid is tougher than you think. I have only hit my doubler skid like 3 times, and yes you can really mind f these crossmbers, try not to.
