Need a measurement. Help

So I'm in the process of dropping my Magnum 360 into my 73 Dodge originally Slant six
seems that all the Schumacher motor mount conversion kits are out of stock for the last three or so months at all retailers..

I picked up the cheap Summit L A Car pan and would like to know how high off of the Factory k-member the oil pan sits when the engine is installed so I can get an idea of how high to set my engine so I can go on with building my tranny crossmember

I hope that makes sense.
Otherwise I would be on hold until I got my Schumacher mounts in and no telling how long that's going to take..

Thanks in advance
