Has anyone heard of modding a front diff by cutting off the top mount for a lift kit? I got a diff this weekend to replace the one in my truck, and I didn't notice it until we were trying to shove it up into the truck, but there is no top mount. On looking, someone cut and ground the mount off, and from the looks of it, it doesn't appear to be fresh, and it wasn't obvious. We were thinking maybe it was because it came out of a gasser truck, until we noticed that it appeared to have been cut/ground.
