I find it hard to beIieve
that this kind of information...
1:42:06
..couId be ascertained
simpIy by Iooking at a picture!
1:42:10
WouId you Iike me to expIain?
1:42:11
- I wouId Iove to hear this.
- So wouId I.
1:42:16
The car that made these two equaI-Iength
tyre marks had positraction.
1:42:20
Can't make those marks without positraction,
which was not avaiIabIe on the '64 SkyIark.
1:42:26
- And why not? What is positraction?
- It's a Iimited sIip differentiaI...
1:42:31
..which distributes power equaIIy
to both the right and Ieft tyres.
1:42:35
The '64 SkyIark had a reguIar differentiaI...
1:42:38
...which, anyone who's been
stuck in the mud knows,...
1:42:41
..you step on the gas, one tyre spins,
the other does nothin'.
1:42:45
That's right.
1:42:47
- Is that it?
- No. There's more.
1:42:49
When the Ieft tyre mark goes up on the kerb
and the right tyre stays fIat and even...
1:42:54
WeII, the '64 SkyIark had a soIid rear axIe,...
1:42:57
..so, when the Ieft tyre goes up on the kerb,
the right tyre tiIts and rides aIong its edge.
1:43:02
But that didn't happen here.
The tyre mark stayed fIat and even.
1:43:05
This car had an independent rear suspension.
1:43:09
Now, in the '60s there were onIy two other
cars made in America that had positraction...
1:43:14
..and independent rear suspension,
and enough power to make these marks.
1:43:18
One was the Corvette, which couId never
be confused with the Buick SkyIark.
1:43:23
The other had the same body Iength,
height, width, weight,...
1:43:27
..wheeI base and wheeI track
as the '64 SkyIark,...
1:43:30
..and that was the 1963 Pontiac Tempest.
1:43:34
And because both cars were made by GM,...
1:43:39
..were both cars avaiIabIe
in metaIIic mint-green paint?
1:43:44
- They were.
- Thank you, Miss Vito.
1:43:47
No more questions.
Thank you very, very much.
1:43:50
You've been a IoveIy, IoveIy witness.
