I installed this B&M Mega shifter many years ago and I also love it. I say go with the mega shifter I don't think you will be happy with that one in your link.
I know you can't see how it's mounted but it's on the floor of the cab not elevated at all and it's the perfect height for me.
As mentioned I'm not sure if you have bucket's or bench but in my configuration it's an awesome set up! I can bang through every gear and never miss any and it's got reverse lock out.
I also hooked up the PK/NU Safety sw. and the reverse light.
Good luck.
