All,
If you want to stick with the driveshaft, there are a couple of logical
points to mount this thing. Either at the transmission end (ie on the
tailshaft - a pain to get at generally, with the drawbacks mentioned below)
or the differential end (my choice - there are already bolts there that you
can use to start the mouning bracket fabrication.
Just my opinion - if you don't like it, I will give you a refund of the full
amount paid for it!! ;->
