I know the xr4i ones are so yours should be ok , the hole in the arms are the same size the arbs are the same thread on the end. The chassis mounting rubbers are different sizes 22 24 26 etc and the brackets differ too.

I would worry more about the bushes and brackets on the chassis rails mate.

If yours are too small you'll either have to cut at the floor above to get at the captive nuts or some folk have filed out 2, 3 mm of the larger replacement bracket to suit the original captive nuts - if you do this you will have to use allen key type bolts not the standard bolts as you wont get in with a ratchet to tighten them up.

Not sure if i like the sound of filing the bracket myself. But has been done a few times on non Cosworth shells.

You can get poly bushes to fit the bigger ARB into the smaller brackets. This negates the need to muck about with the mounting holes or brackets.
