Wow, there is Life, Jim! So good to hear from you Scouser.

The motor mount is from WLToys. You can go to Aliexpress, then just do a search for "wltoys motor mount". They are cheap as dirt but are meant for the 3650 type Brushless motor whatever that means. I only know 540 & 390. Haha. Seriously, I think a 540 motor would go on fine also. The motor/ESC combo I used comes from Surpass Hobby KK series. Again, go to Aliexpress, then search for that if you like. I am not familiar with the Forum's rules any more, so am not going to post any links here. Sorry!

I would not say the motor mount was a "Direct" Drop-In Solution, but those are threaded holes at the bottom of the mount. I kept the original Engine mounting plate, and just drill a few holes. That's it. I will try to post some photos later if it helps.

Here is the video of the truck running my home-made 3S LiFEpo4 pack. I did not get to really push the truck but then she is an old lady and should be respected. Haha.
