U-20 cam sprocket chock

[bill/liz wessel <bwessel@itis.com>]

Guys,

Got a "customer" with a 2000 head that needs to come off. The "evil L" is
gone. No way to hold up the sprocket and chain from falling to the bottom
of the pan.

Can someone provide the dimensions of the wood tool (don't laugh, this had
an actual Nissan number, it was a factory tool) that is used to chock the
chain and prevent it from falling while you remove the head?

Thanks in advance.
