From Delfex, you need to order by phone.

I loosened the bolts and now the vibrations are goone when driving. There is a little more vibrations on tickover than with the worn original bushes, but you can't expect anything else since the engine is prehistoric.

So if you buy these, don't tighten them up real good, just make sure they are secure. Loosen them a little if the vibrations are too bad.
