bigmacdaddy is right, however after you've bought a few tanks that don't fit, like me, then that custom $ tank is not so expensive. I have found you must be very careful when measuring. On mine the frame rails were wide enough but I didn't notice the spring shackle nuts were protruding just enough that my Blazer won't work.
