I snapped my driveshaft and nothing bad like that happened
the end of the shaft that was still connected to the axle lodged itself in the back of my cab. it sucked
having a drive shaft brake at speed is a very dangerous thing. race cars have to have a drive shaft loop to keep it from riping the cab apart
I have a narrowed limited slip Ford 9" that I had under my V-8 Toyota project. I have been parting the truck out. It is narrowed to stuff 20x10 Prowler wheels under the back of the Toyota laying body.
Yes its a direct swap as long as you are using 4cyl type rearends. I found this stuff a while back when I trashed the differential in my truck. I had a good diff. in my 4wd parts truck, swap was easy.
