That model is the default model for flippymodding and SPS has released a video about the process.

Just placed my order ..
It is coming from Kazakhstan ..so hopefully it survives without incident.
"Panasonic JU-475-5AK0 5.25" Vintage Floppy Disk Drive + Cable FDD Tested"
I guess £40 isn't too overpriced since £15 of that is postage.
Just hope my modding skills are up to the job.
I have a dremel and a drill press ...so hopefully I can just use a drill bit 'reversed' to push the brass bushing.
wish me luck.

Just be carful with the alignment. Getting it right without an analogue alignment disk can be a nightmare.

Is it possible to perhaps get an image of an alignment disk I could create prior to modding ,on my currently fitted Panny Drive ?...just in case..
always good to be prepared.
Perhaps you or another forum member could help here ?

Think about how alignment disks work and then let me know if you got it, otherwise I'll reveal it. ;)

Obviously I dont know specifics ..but I have used an AppleII alignment Disk before ..but this was only rotation speed adjustment ..
I assume right or wrong ..that once the first track/sector (zero) was identified all other would naturally be aligned..
or possibly aim for a mid track as with the C64 track 18 ..
Which i guess reduces tracking errors < track18 or > track 18


I may not understand fully ..but can follow instructions...and am eager to learn.
lol

The point of Panasonic mod is that to perform it you don't need alignment tools if you follow the procedure correctly. And do NOT touch the two screws used to hold the stepper motor to the drive frame. :)

Is there a detailed list and description of the different kinds of mods somewhere in print (not video) format?
