My model bike is a NSR 250 MC18 SP TERA 1989 R6K

I'm seeking for MC18 dry clutch seal part No : 91204KV3781 ( 68 X 84 X 8 ) to complete my engine build.
Does any one have ?? or could look if could source this seal for me in stock somewhere ???

Maybe a used good MC18 cover included this seal in good condition ???

I just need this seal to close my engine , but it seems that this seal for MC18 is NLA from Honda
if someone can source a good clutch assy for me MC18 included this seal ???

Another solution does any onw know if I could fit clutch assy from MC21 in order to use exisitng seal from Honda 69 X 84 X 8 partn No : 91204KV3841
which is available in order to complete my build ,

please revert what you can find ????
