I fit a new rubber couling for the transmission

I've got a little problem :

1 side is stamped "drive shaft side" : so this side should look the rear of the car ; it's ok

but there are 2 type of "hole" for transmission side so you can have 2 positions :
you can see it on the picture



can someone explain me how the rubber coupling should be fitted ?

thanks a lot

 

It's going to be the same as the one already fitted so just copy the way that is fitted.
Looking at the picture I would assume that one end of the prop that fits to this will have machined lugs that fit into the slightly recessed bearings whereas the other side will not.
tabetha

 

the rubber coupling for the sierra 4WD is different and do not have the machined lugs ...

so don't know how to fit it.

if you see the picture :



need to know if I should use the red or blue holes for the torx studs (coming from gearbox transmission)

and so witch hole (blue or red) to fix the transmission shaft with the studs and nuts

thanks

 

up

nobody change it ????
