The ground effect Chaparral was mentioned and that looked much like a Lotus 79 clone (as indeed were most of the effective F1 cars in 1979!)
I also recall there was the Longhorn chassis said to be a Williams FW07 built under licence.
A decade earlier the 66 Lola Indy winning design became the 67 Italian GP-winning Honda.
Most of the Brabham Indy cars of the 60s appeared to be beefed-up F1 designs , as did the early Lotus', and of course there was the 56 Turbine....
But how many other chassis types have actually competed in both F1 and at the 500 with reasonable results since the dawn of the "funny car" era in the early 60s?
