Currently the 1969 Lola #6 Sunoco T70 Mk3B is placed in the Prototype Group Racing division. This division is filled with CanAm-Racing and Group7-racing cars.
In it’s period the Lola T70 Mk3B raced in Group4-racing and Group6-racing. Cars of these groups are represented in the Vintage Le Mans Prototypes division.
I think the Lola would be a better fit for this division, racing against the cars it used to share the track with.
