Got this Ultima II for $20 off ebay about 6 months ago, Judging by the front shock tower I guess it started its life as an Outlaw Ultima Truck and then got converted to a buggy.
Original auction pics:


I replaced the bent front shock tower with one from ST15 (with the anodizing removed) and installed 3Racing ZX5 shocks. I had a Triumph gearbox which I intended to use on my Ultima vintage racer but found out I'll have to cut the rear part of the body to install it, which I had no intention after all the hard work I spent painting it (Hey, that's a justifiable consideration in vintage racing!), so in it went without too much fuss.

I replaced the viper body that came with the car with a Turbo Ultima body in bad condition that I got in a lot. It was broken at the rear body mount area so I used scrap lexan to fix it, I also lengthened its sides so it would fit the Ultima II longer wheelbase. The side windows were painted so I cut them out.




I finished it off by painting it from the outside and adding nets to the side windows



I also strengthened the upper lexan fix with four 2mm screws

On my next crawling meeting I'll take it with me and have some bashing session as well!
