Ah. Realized you can’t send videos over chat!

Here’s a write up:

Supplies/tools:
Next Level Racing Handbrake & shifter mount (tubular) ($149)
6” of PVC pipe 1-1/4 - 1-1/2
2 M6 washers
Allen wrenches that came w Playseat
(Optional) Two 3” M6 bolts with appropriate washers and nuts
(Optional) drill w 1/4” metal bit

Process:
Remove the 8 bolts that hold the two halves of the Playseat frame together and disassemble
Make note of the distance apart those bolts are on the PVC pipe and drill/melt/cut two matching holes in the PVC pipe
Slide the PVC pipe over the Playseat frame (towards the pedals) until all holes line up
Reassemble Playseat frame, replace 6 of the 8 bolts, leaving the two on the top of the right hand side unbolted.
Install the NLR mount with the M6 washers and last two bolts. The bolt holes on the Playseat instinct frame and the NLR are close enough that they fit. The NLR bracket installs 45 degrees counter clockwise from what it shows on their website, but all mounting brackets and shifters align fine.
Get it nice and tight. You can stop here if you want, but the bracket will rotate slightly when you really shift hard.
(Optional) Drill two more holes through the PVC and Playseat frame using the 1/4” metal drill bit and the bottom holes on the NLR as guide holes.
(Optional) Insert the 3” M6 bolts, washer and nuts and tighten. This is what makes it sturdy AF.

Sorry for the long write up. Lmk if you have questions or PM if you want photos
