Anyone got the diagrams for the engine stand used for dropping the motors on these vehicles?

I'm looking at making a engine stand that you can jack up under the 996 motor when its on a two post ramp. Then raise the two post ramp and the engine stays on the engine stand.

Also going to make the engine stand raise up and down.

Could do with some diagrams as I can get my engineer friend to knock one up.

Cheers
Martin
