Matt

I would like to offer one other piece of advice regarding supporting the car using building block materials.

After re-reading your excelent article (PDF) it reminded me of a past incident where a neighbor's car fell (luckily not on top of him) while supporting with a cinder block. Although these blocks can take a lot of weight, their design use application is distributed.

Having a concentrated weight on a relatively small surface area of a brittle block will cause this block to crack and shatter.

Again, thanks for your excellent instructions. This site should post them in the DIY section.
