The bigger issue though was that the mushroom peg for the waste swivel is actually further forward on the ER chest than it is on Siege, so the leg treads would end up being way lower than the backpack treads and nothing could lay flat. The ER crotch is actually super long though so I was able to carve a sliding channel into it that I can use to raise it up in tank mode. I even left a few notches along the sliding track so it actually locks into position for both tank and bot mode, so I'm pretty proud of myself there. The backpack also needed a few bits carved out so it could fold flat. Because of what I needed to carve, that part actually locks into place too so that was convenient. Also had to do some shaving to a few tabs and the sides of the chest but I think that may be more because something was slightly misaligned when I put things back together. Point is it transforms just fine now.
All in all, pretty happy with it.
