Search Ebay a lot, you might luck out.
If you can get good photos (online maybe?), a local sign / decal shop can probably make you good ones. I have an old 80s Sannino frame that needed new decals. Velocals had some but they were nothing like the original. So I just grabbed a couple of photos of the frame from online searches, estimated the dimensions, etc. and the local sign shop made what I think are excellent facsimiles. There was a little give and take in the design, but they were happy to work with me and it ended up being less than $50 for two sets. I later found a (very rare) OEM set on ebay and they are virtually identical to what the sign shop made for me. I haven't bothered putting the OEM ones on because of that.
