In composing the various installments for this site's Service Index, I only found reference to snubber equipment in the following articles:

* Clutch Chatter (1600-1), in SL Vol. 12, No. 13, shows a rather basic (early) design.

* Clutch Chatter (1600-1), inSL Vol. 13, No. 1, shows a superseding design (a 17th Series retrofit) with two socket joints.

* Loose Motor Snubber Links (1700-1-3), inSL Vol. 13, No. 1, shows only a partial view of a socket joint and a cylindrical (transmission) insulator.

* Clutch Chatter (1600-1), inSL Vol. 13, No. 14, shows actual view from under car, but I can't see any snubber, there.

* Engine Roughness (18th Series WITHOUT Econo-Drive) , inSL Vol. 13, No. 19, shows a design like what's shown in images attached to posts #2 and #7 above - rubber insulators, sandwiched between washers and nuts, on a threaded rod.

* Clutch Chatter (all models), in SL Vol. 17, No. 16, but no illustration is provided.

Sorry, there's no clear-cut update in any of the service newsletters. I'm wondering if this was covered in a Technical Letter, but we have a few examples of those, here.

Meanwhile, the parts books are about as clear as mud.

I'm not all that famillar with this aspect of these cars, but it looks to me like the design with the simple threaded rod and rubber insulators/bushings was first used on 18th Series cars WITHOUT overdrive (replacing socket type formerly used with 17th Series) and carried over, with similar application, to 1951 and 20th-21st Series. This design then appears to have been expanded to ALL transmissions for 22nd-23rd Series - standard, overdrive, and even Ultramatic.
