Hello Bobby, I got your PM and it took me a while to get to the bottom of it. So here it goes.
You can get the JDM specific ones and I did order some at some point for someone else so not in my tables of parts to check. But I am sure that this should fit a 12V 90 engine:
Bar Comp, Step, Part Number: 50610-GT0-700
Check with your local Honda Dealer or any other online Honda Parts dealer that you know of. Mine was bought from nutjob.ie.
CMSNL also has it available: https://www.cmsnl.com/honda-c90cm-1999- ... 610gt0700/
You can order it yourself, yes. I hope this helps.
Kind Regards,
George M.
