Funny Looking G21A

[TXANM]

First post, new to the hobby. I figured it was time to get yet another hobby & have been looking for a nice golf cart to tinker with. I found this little gem for $1,800 off craigslist yesterday & jumped on it. I was amazed how effortlessly it ran in the cold. It was about 15 degrees outside & the cart was sitting on the side of the house & had obviously not moved in some time. It ended up firing up & running after a small shot of choke.

I was a little stumped when I started the cross reference on the cart though. The serial number JR6-2... implies it is a 2002 G21A Yamahauler. Funny thing though, it is a regular cart rear, not a hauler. Obviously it has been modified beyond just the lift kit. My question is for future modifications. I am not sure what front & rear I have now to get some lights, skins, windshield, etc.

What is logical here?
1.) The previous, previous owner swapped out the rear with a standard cart & threw out the dump bed.
2.) The previous, previous owner took two carts & moved parts around to build this, and I have a mixture of cart shell, basic frame & gas engine.
3.) I will never know.

Thanks for the advice & I can't wait to start to dump good money chasing this one!
