Hi Mark:
Thanks for the complements- unfortunately my model pictured had been damaged after I loaned it to a local hobby shop for a display, I haven't gotten around to repairing it but probably should.
I am assuming that the builder in your photo used the same plastic model kit that I used which is the Revell-Monogram Reynard (but they used the optional "superspeedway" wing and nose set-up, oddly enough with the "road course" rear wing! Something that just wouldn't happen in real racing.)

This kit wasn't that popular in its day, so you'd think that there would be tons of them available on the secondary market? No such luck- I have been trying to snag a few more examples from ePay (at reasonable prices of course!) for quite a while without a trace of joy.
Now IF we could find the kits, there is a wealth of aftermarket decals for them, nearly every Champ Car of significance that raced that season... I'm sure that the irony isn't lost on you?
Note also that your group photo apparently shows 2 other Reynards- the Bryan Herta Shell livery and one of the Dan Gurney-TRD entered cars (as pictured in the box art above.) The AAR Reynards were the apparent test bed for the 997 Eagle Champ Cars, which IMHO if beauty equated to success, would have won every race in the 1999 season. IIRC there is only one 997 that survives, that being the "customer car" originally sold to Robby Gordon's Menards backed team, which had the lovely metallic blue paint covered over with John Menard's trademark garish livery.
There is quite a thread on www.F1m.com about these kits with recent input about how they were under-rated by model builders at the time.
Otherwise my scale racing activities have been limited by taking a full-time college class load; the goal being to update my professional skills so that I might someday again be a productive member of USA society and taxpayer.
I note with amusement that your friend and mine in Tacoma Washington is planning an endurance race for Scaleauto 1/24 GT cars this fall. I'd strongly urge you to consider getting a team together and participating. Really. Seriously.
