I had a dream about your setup........ Here is my input, you may like it.
This has to do with screen placement. First off get rid of the wooden cup holders, they look ultra ancient and tacky. Plus you will need the room for your screen. Basically sell the Lilliput and buy the VM70. Picture is below:
Now you may ask, why go to that screen? Well because it also comes with this:
So rather then having a hard time putting the EBY701 in, you would pop the headrest cover into the dash, it would hide any cuts because it has a lip and I think it would look alot more stock and maintain the interior. I would just sell the EBY701 for $145.00, which is the cost of the VM70 with free shipping.
I use the headrest covers in my install and they made it so easy to put the sceens. Here is a picture of mine.
See how it sits OK in the seats. Now because the area under the cup holders is flat, it will sit 100% flat.
Here is a picture of someone with it installed in the front, he just doesnt have a bezel though, you wouldnt need a bezel, just cut a perfect hole for the back of the cover to fall into.
The screen looks similar to the EBY701 performance wise. Also if you worried about loosing cup holders, you can always buy a center console made for vans with cup holders. They are pretty cheap.
