Actually its been holding up great. I've got over 20k miles on the swap now over 2 years. Nothing major, a couple ripped cv boots which may be because they were junkyard sourced. I highly recommend adding a HTOB spacer. ZZP sells them for around $50. Sits behind the HTOB and moves it closer to the clutch by 1/4" for earlier engagement and longer life.
Aside from engineering the trans mount, the hardest part is getting the clutch pedal mounted and situated. The pedal arm needs to be cut & welded into proper position as well.
As far as the mount, the low-profile mount I fabbed up works great. Only modification I made was adding rubber bushings under the nuts at the bottom to further insulate the mount from the frame. On an aluminum subframe, it might have to be done a bit different. Might be able to drill two holes and bolt it in the same way, but I haven't been hands-on with an 04+ subframe so I can't say for sure. I'm not a fan of the modified 4T65E bracket method that requires tubular control arms as the mount sits outside the frame. An extra $650 that could be spent elsewhere.
There really are half a dozen ways you could fab up a mount but I can say for sure the one I made does the job. 3/16 steel plate holds up well so far.
I have also just finished taking the time to document the changes to the tune that are highly recommended for a manual swap:
Idle speeds in-gear changed to match P/N as its going to be wired to be in D at all times now. ( I actually added a toggle switch to change between forcing it in D or P, since P is needed for a crank relearn procedure if you need it)
DTC codes changed
And finally zeroing out all the auto trans stuff:
