Not sure if I care for that body, but I can certainly make bumpers out of tube or rod and weld them up. Not a master welder, but I can work a mig welder on steel very well. Welding sheet metal on cars trains some finesse due to material thickness.
I had planned to make some serious bumpers and roll cage for my savvy 5t build, try to keep the body sorta safe...
The HPI Blitz bodies are the widest/longest and will fit 1/8 buggy chassis the best , then the AE SC 10 bodies . Anything made for the Slash will be a bit short .
The Rear bumper for the Slash 4x4 is pretty easy too mod too work as is the RPM front bumper for the 2WD Slash .
