Not sure how similar the 260 is to the 280, but watch out for these gotchas!
Need to remove locknut on steering rack bushing holder from the top, prior to undoing the bolts from the bottom.
I had a **** of a time (so have others) getting the new poly insert to roll around into place. Not enough clearance below oil pan. Much better to do this if the engine is out! Unbolting an engine mount and jacking engine a bit might help a lot. I didn't jack engine, but I sure did grunt and fart and cuss at those rat bastards till they finally worked into place.
Note left and right are not the same.
Good Luck!
Later! -------- Al
