Depending on your budget there are some secondhand ones on Ebayyyy.
They look like they need a clean at least.
I’m not sure if the Showa shocks are serviceable.
I have mentioned this before....With Euro Ebay sellers....most will willingly "haggle"...and the one RobG has listed is open to offers.
Make a reasonable offer.....then be prepared for some "to and fro" messages/emails (offer/counter)
Again as RobG pointed out you may want to find out the cost of a shock refurbish....and consider if a non-stock item might be more worthwhile...
