Crib Blocks

Here is a Google Sketchup of a Crib Block I plan to use to support my floor jack(s) when raising the van.

Here is messy assembly of a crib block for supporting the van itself46293

I have drawings of the components themselves and will post them if there is any interest.

The idea isn't mine. It came from this webpage: http://www.myturbodiesel.com/1000q/multi/wood-block.htm

I plan to use the idea with this other idea I found on this forum.

My van has a blown head gasket or the intake manifold needs replaced, again. So I'm considering raising the van and dropping the motor from the bottom. Haven't done it yet.
