Has anyone here built an electric MK4 with a Tesla drive unit?

I've seen this one. They used a Tesla drivetrain but not a FFR chassis: https://www.diyelectriccar.com/threa...ce-car.180761/

Also this one. They used an MK2 but not a Tesla drivetrain:

I'm planning to build an MK4 build with:

- Tesla Small Rear Drive Unit
- EV Controls T2C controller
- LG Chem JH3 batteries (fourteen 25.6v packs in series = 360V and 500A)

I'm looking at products from Zero EV, HSR, Stealth EV, Thunderstruck EV, and EV West.

Any advice???
