hello i have a chevy 6400 with 235 ci motor with 33000 miles on it. truck is mint for never being restored


here is my problem. last fall i was backing up with a load of stone in a wet yard and broke the rear end. it has a 2 speed rear.

i havent pulled anything apart yet but wondering what you guys might think have happened?? also i have 2 4100's would the rear end from the 4100 bolt right in? or where can i get parts for the rear end?


my 6400 is 16000 gvw my 4100's are 11000 and 14000

i also need a gas tank for my 4100 does anyone make one?

thanks
