Hello all,
As you may recall, I am trying to fit a pair of Sapphire front spindles into a Merkur XR4Ti. With all your help, I have learned a good deal. I now have an idea that I would like to run by you all.
Background:
1)I have been told that the Ford Grenada/Merkur Scorpio TCAs are the same part as on the Sierra Cosworth (the Sapphire spindles I have use pinch bolts, but I'm going to assume that that is the only difference from the Sierra Cosworth TCAs).
2)The ARB on the Merkur Scorpio is 27.5MM thick, very close to the Cosworth dimensions.

It would be very expensive for me to source a real Cosworth ARB here in the States, so I'm thinking of using one from the Scorpio/Grenada. One possible problem that I forsee the the length of the "arms" on the Scorpio ARB. I have had an XR4Ti ARB and a Scorpio ARB side-by-side, and the Scorpio unit is both wider and has longer "arms".

The extra width should be no problem when used with the Sapphire TCAs, but will the length work? Has anyone had a Cosworth or Sapphire ARB next to a Grenada/Scorpio ARB? If so, how do the dimensions compare?
Thanks and regards,
David L.
