it looks like the hole in the crossmember is a bit larger than the sleeve and that allows the torque arm to slide front to rear and side to side.
Would this have any downsides?
If you're planning on limited travel and body roll, nothing wrong with it at all. The bushings even give you the opportunity to "tune" how the arm hits the chassis slightly. Just be careful when jacking the car up, etc. not to over articulate the bushings.

I understand after seeing the picture - Thanks. If the link was oriented to be in tension during braking then I guess the same issue would surface during acceleration when the link would be in compression?
I've never been a fan of the implementation of the Griggs torque arms or watts links. They do seem very durable and functional on a race track where you don't care about noise or vibration - they just need to work and can't break.

Is your torque arm built from round tube or square? If square we have a machined slider insert with Delrin bushing and poly mount you could use. It fits into a 2x2 x.120 tube. This is what we use at the front of our torque arm kit. The slider tube slides on 6 inches of Delrin equipped with grease channels and a grease fitting. The whole setup is bind-free...

Yes. That's one argument for using the sliding front mount. IMO, the double spherical is a little more compliant over bumps, as the double mount has no true center of rotation. Probably splitting hairs...

Boy, now there's a really interesting idea... You could probably find a flange mount ujoint and bolt the flange to a plate on the crossmember and use the whole works, ujoint and all...

You'd have to find a way to accommodate the twisting motion as the slip joint from a drive-shaft will be grooved.
