Looking for Yamaha tool YM-01067

[Elimax]

Hi all:

I hope everyone out there is doing okay.

I'm transplanting a 1987 FZR1000 cylinder block onto my bike, and I'm using the Yamaha FZR1000 service manual for a guide. I'm trying to stabilize the pistons when lowering this cylinder block onto them, and Yamaha says to use tool YM-01067 (or what they call a "Piston Base") to do so. (Note: I already have the piston ring compressors I need.)

For the life of me, I cannot locate on of these tools online. Do any of you know where I can find one, or who sells a suitable replacement for it?

Thanks for any help you may have!
