Steve,
This photo shows the McLaren team testing with Denny Hulme in the #5 M8 Can-Am car.
That was May 1968 and there is no chicane or grandstands on the right so it must have been removed in 1967 when the grandstands were also dismantled.
Perhaps the chicane was a liability for the driving schools that operated back then.
I suppose you could put in a temporary chicane for the day just to add to the fun.
Ken.
p.s. I am glad you liked the thread.
