Bafang BPM 48V500W Clutch Problem

hi Guys
I have an old Bafang BPM 48V500W Rear Driving - RPM : 328 from BMS Battery
the motor runs ok but I believe the clutch is faulty
you have to pull away very slowly otherwise the motor makes a loud screeching / clicking noise
it fine once its up to speed
I opened up the motor with the special tool took out the clutch, cleaned & checked the 3 white plastic gears (all ok)
re-greased the gears & refitted everything & it still has exactly the same fault
I can't find anyone selling the correct replacement clutch (please see attached pictures)
its the older style clutch with the 4 key slots in the central shaft
I can only find the new style clutch with the 1 key slot online to purchase
does anyone have a clutch to sell or can you tell me where to get one?
Thank you in advance
Dylan

May not work:
"There are two versions for BPM clutch, and we only have the new version clutch, please be noted."

Looks like it may have become hard to find even 7 years ago, based on the post about halfway down here:

thanks for the reply gents
Unfortunately green bike kit only do the new style BPM clutch which is different to the old one.
I have had a search on ebay & aliexpress with no luck.
The old style clutch that I need has 4 keyway cut-outs for the central shaft.
The new clutch only has one & will not work.
I'm hoping that someone either has an old style clutch that they want to sell,
or knows where I can purchase one.
Fingers crossed someone can help me.
kind regards
Dylan
