Are these the results?
https://www.racingsportscars.com/results/Le_Mans-1962-06-24.htmlWas it in the GT2.0 class ? There are only two entries in that group, with the other, a AC Ace Bristol not finishing. Or are groups and classes different things? There is a 2 litre TVR Grantura that might also have been in TOK 258's class - though that did not finish due to a water leak. But the TVR is recorded as P2 rather than a GT2.0. So it looks like it was first out of two or three cars in its classification.
https://www.experiencelemans.com/contents/en-us/d132_1962_Le_Mans_24_Hours_Competitors_Results.htmlgives a slightly different table and names TOK 258 as the winner in the GT 1601 - 2000cc class.
150 km/h average (93 mph) for 24 hours seems pretty impressive both for driver(s) and car in any case.
