I don't have any to compare but there should be substantially more information on those wheels than what you've mentioned. There were 2 vendors for them I believe Enkei and Modern. I've always thought that for sure the Enkei had the "brand" cast on the wheel back-side. I've never checked or seen information posted regarding the Modern. If there's no "branding" maybe it would be safe to assume it's a Modern wheel and you should be looking for '84 - '85 replacement to go with yours.
Check all of your wheels closely for these codes on the back-side somewhere: FJ or FM on the lefts and FK or FR on the right. Those would be early Modern I believe.
AN Enkei might have an XDN on the left and XDP on the right.
Regardless I believe there should be more!
