Trying my best to add pics, will figure out. The s-10 chassis swap woes. Would like to share. Front track width. We were able to solve(me and my 5-year old boy,Matthew Sixx, he is the sixth of six, therefore named.) we used 15" rims 10" wide, 3.75(3.73or3.78)backspacing on the rims. 15"x12"wide x28" tall tire on all four corners(can rotate,short of directional tires,but you all get the idea) clears really well and fills up fenders like we like. Corrects tracking like we wanted. Keep in mind we used F-5 front fenders,don't know if we woulda got away with on F-2 and smaller? Also swapped rear end with the 4" wider Bravada rear end. I'll shut up and listen and try to figure out how to post more pics for anyone interested.(maybe I'll ask my 5 year old?) thanks, hope to help.
