In my humble opinion, you need to get rid of the front wheel spacers, and convert the front to big bolt pattern. That way you can buy whatever wheels you want. I had a BAD experience with those bolt pattern adapters 50 years ago. In 1969, I bought a new 69 340 Formula S Barracuda Fastback. SBP wheels were HARD to find. After about 6 months, one of the adapters came loose and caused a lot of damage that was of course, not covered by warranty. I would personally get rid of them ASAP. I know that others will say that they are no problem. All I can tell you is what happened to me.
