I was going to tell you Velocals until I saw that you said they only carry 1985 decals. I did reach out to a seller on Etsy. "CustomDecalsByNikki" and she said that she could reproduce bike decals with no issues. However I did not end up needing decals for that particular project in the end so I cannot vouch on the results. Maybe it is worth reaching out to her to see if this is an option…
