    Has anyone else had a problem with the Moog RK621329 UCA hitting the 'inner' part of the tower? The new UCA body extends over 1/4" more past the shaft than the ones I took off. There were no spacers when I removed it and I don't think it is a good idea to add any. I am considering just grinding off the extra material on the body, anyone ever had to do that?

    Is the bushing down tight on the arm? Should be torqued to 40 lb-ft.
    Moog has been been turning out some real crap since they got bought out and many of their parts are now made overseas.

    The bushings seem to be fine and the shaft appears centered in the arm. The problem has to do with the body of the UCA hitting the shock tower preventing the arm from moving. Note how much more the new one extends beyond the bushing than the old one.

    I'd just cut it back till it cleared and move on...

    That 90* fitting will probably be against the spring tower, you'll be lucky to fit a grease gun on it. There are shallow ones that work nicely. I pulled arms on My Fairlane, removed plugs, greased with fitting & reinstalled orig arms with the plugs.

    I would hammer it down some and then hammer some clearance in the shock tower part.

    I would think in the same terms. Don't cut holes in the shock tower for the grease fitting. It's been done quite a bit in Falcon-chassis cars and is a common source of shock tower cracking.

    Drilling a 3/4" hole in the tower isn't gonna hurt anything...

    There are people who will take both sides of that issue for sure.

    Well the "proof is in the pudding". My Maverick will be 50 years old in January and has never developed any cracks in the spring towers, and the holes are the size of a golf ball. This was done by some shop before I got the car (the first 8 years of its life), not by me. I would never have made them that large. I covered them with sheet metal so they are not visible, but they're still there...

    There are 1ΒΌ" holes cut in my Cobra, been there since early '70s.

    I got the arm, there wasn't an issue with the grease fittings. I did put the 90 fittings on and they work fine. I got the arm to fit by cutting a bit off the arm near the shaft so if would clear the tower. Everything moves just fine and no holes in the tower for grease fitting.

    I assume the other side will be similar but haven't got it torn down yet.

    For the grease fittings on mine I cut the holes then welded in big washers with the center holes lining up with the fittings. Don't use them anymore, though, with my tubular control arms.
