Instead of going crazy with the Taco, I found a complete ready to roll Formula Toyota buggy on the local craigslist. Looked at it a couple times and went for it. He even delivered it!
FToy Chassis #43 on a 84-84 Pickup frame
22r running on propane
Dual Transfer Cases with 4.7:1 gears in the rear case
4.10 gears, welded front, spooled rear
Trail Gear Rock Assault rear housing with disc brakes
well used 38.5x14.5x15 TSL SXs on Allied steel beadlocks
Chromo shafts/birfields in the front end
Once it was it it's new home, I pulled the back seat out, ordered up some new 5-point harnesses, and started adding some tube. It felt open and 'scary' with no internal bracing. So an X-Brace went in behind the seats with some correctly located shoulder harness bars as well.
After getting it safe and comfy, cleanly ran thru emissions and transferred the title and tag. Yes, in the Wild West, this is a special construction ATV with On and Off Road Stickers on the small MC plate .
Dragged it up to Table Mesa just north of town for a quick shakedown run. Sorta flexed out on the rock pile and messed around on Lower Terminator. This is a FUN Rig! Next trip out was a night run on Raw Deal and Lower Terminator. Point and shoot at times, then unaware of where the hang up points at others, and weight distribution...ooooops, glad there wasn't any sheetmetal/glass.
