Jim, I've seen a Basso catalog that shows the '86 Gap as a frameset. Perhaps that explains why there are different builds. Earlier catalogs show the Gaps spec'd with NR or Super Record groups.
BTW, how does your SLX compare to the other bikes in your stable?
Anyone know what happened to the Basso brothers?
