Thank you for the valuable information.
I know the original post was made 8 years ago but the information shared still holds value and importance as the snout repair is now widely recognized.
I was astonished when I first found that such a solution as PDM TSK1 existed. Despite the fact that the kit has been around for over a decade, I could only find very limited numbers of reviews.
Doing an extends research, I found out that the throw out bearing supposed to come in the kit is Toyota 31230-32060. The bearing height and the outter diameter of the lip is similar to that of a BRZ TOB. Unfortunately, the actual kit seems to be using a Chinese imitation of the Toyota OEM TOB.
I have decided to source out a TOB locally and just use the sleeve from a Clutch Pro kit or measure up the diameter of a Toyota OEM TOB retainer and get one custom made.
