Not sure if this all correct, but from what I gathered -
Ginetta sold cars to Manor, for 2 entries, plus spare packages
Ginetta have lots of other interest, but nothing confirmed (AFAIK)
Perrin sold 2 cars for entry, plus another as a spare package
SMP Dallara is still on the cards
Morand has talked about engines, but not chassis (Perrin?)
Dome are involved with something
Edit: How did we get into this on the IMSA thread?
