Porterbuilt LS engine mount measurements

[hookedonchevys]

I was wondering if anyone had any Poretrbuilt LS motor mounts kicking around and could help me out with a measurement.I have the old small block chevy mounts right now but have decided to go the LS route and it might be a bit before I get my engine mounts from porterbuilt.If anyone could run a straight edge the same as I have in the picture to give me a measurement to the holes on the LS mount it would be greatly appreciated.I want to move forward with building a transmission crossmember and am wanting a rough estimate to where the transmission is going to end up.
