Carl helped me with this installation on Sunday, and here are a couple of things we learned.
I echo Don's suggestion to use longer bolts (see red arrow in attached photo). 25mm should be about right.
My car is an early one (chassis #334) and the cutouts for the engine mount bolts are much smaller (and rectangular). Note in the other photo the red area, which was solid on my car (for both). It took some grinding to open that up to be able to slide in the nut.
So my recommendation is to get a couple of longer bolts and have a heft grinder available BEFORE you start this project.
