Thanks Matt, glad to hear it.
Thanks Nelsonian, especially for the pictures. I do agree, the website is a bit lackluster, it was one of the reasons that led me to posting here asking the question. I feel I would have next to no qualms buying from the wiringspecialists website in comparison.
From what I've seen you can get the JZ's sitting low and quite far back, I had thought about putting a 350 small block in the car, but the sizing and weight distribution was all off, and would need to relocate the Dizzy to get everything to fit right.
So it looks like, from the picture you linked you basically get all the mounts you need + a propshaft. That's ideal for me, hoping everything works with the R154 gearbox. Now all I need to source is a custom exhaust, FMIC, cooling and some gauges!
Thanks for the input guys
