Here are pictures of the process and result, with some details of the process for attaching the replacement Jada 1:43 scale Jeep.
1. Beneath the playfield, find this hex screw that is holding the shaft of the truck spinner in place. Using a 3/32nd size hex key, unscrew and slide this off, putting it somewhere safe.

2. Note the two washers between the playfield and the truck; metal washer on bottom, nylon bearing washer on top. Don't lose these!

3. I pre-drilled some holes in the bottom of my Jeep to make it easier to reuse the existing screws. I lined the mounting plate up to the bottom, stuck a 3/32nd drill bit through the holes to make some marks on the bottom of the Jeep, then drilled where I wanted to mount. You'll notice a few holes higher up, towards the front axle. I initially had the Jeep mounted there, but when I reinserted it into the playfield, found it made contact with the corkscrew habitrail return of the Pteranodon ramp, so I moved it back, which...

4. In order to do so, I had to trim off 1/8-1/4" of the raised plastic portion in the back center of the Jeep. I used flush trimmers to make initial cuts, and then likely some pliers to rip the pieces off, cleaning up as necessary afterward. This enabled enough clearance for the screw on the opposite side of the mounting bracket so I could position the Jeep far enough back to clear the corkscrew habitrail. Note the gap between the raised plastic on the Jeep now and the screw on the mounting bracket, as well as how far back the end of the bracket is compared to the spare tire on the back of the Jeep.

5. I highly recommend putting some hot glue in the doorjamb of either car door to seal them shut, otherwise they may open as you play the game, which could interfere the ramp and/or ball. Plus, it looks silly having the doors flung open hah.

6. Note the distance now between the Jeep at various angles and the corkscrew return.
