Picked up a spydershaft DS and BMR loop from a member on here and need help

[Fallenauthority]

So I placed a WTB ad on here for an aluminum DS that doesnt need a new pinion flange to work on our cars, a member on here PM'd me with an offer to sell me theirs and their BMR safety loop, I buy them, only to realize when I receive them that I need a new pinion flange, which I should have researched and I couldve easily seen the spydershaft needs a new pinion flange to work, so im not too hot about that. But the BMR loop is incomplete, it only has the loop portion, not the part to mount to the body. I am going to shoot an email to BMR in a bit to see how much to get just the part to mount to the body and the hardware for it.
I just want to make sure I am going to order the correct thing for the spydershaft, this is what I have found to order:

Just want to make sure that it will fit to this:

Oh and here is a pic of the "safety loop" that I received:

Do all spydershafts require that cobra pinion flange to bolt the 3650 to the 8.8?

I recommend you call Spyder and have him send you just the flange.

Yeah cause some one already gave him the shaft.
