To All in 300 Land. A word on plating and processing. Black Oxide is a surface treatment that doesn't change the texture or dimensional characteristics of a machined (or ground) surface. Gage and inspection tooling is often "black oxide" coated. Black oxide exhibits poor corrosion resistance. Newly B.O.ed parts are generally oiled after process. Phosphate Coating (almost positive aka "Parkerizing") is a "non-metallic coating" and produces detectable dimensional change. The coating produces a dull-matt -almost rough surface finish and may be applied after other metallic plating has been applied. As I remember (it's been awhile) phosphate coating is used in applications where friction and/or heat is a consideration and may be used in conjunction with dry film lube. Cadmium and Zinc plating both produce a "white" metallic surface finish. They both produce dimensional change when plated that can range from .0001 per side up to .005 or thicker per side. (The customer can specify the thickness.) For some reason, gov. spec.s require certain fastener parts to remain "white" while the bulk of parts cad plated will end up yellow. This is because they are dipped in a chem. film irridite after plating. The iridite doesn't produce any dimensional change to the previously cad plated surface. The really good news is that most plating shops with aircraft/aerospace experience can either perform the above plating services or send you to someone that can. Danny Watts 300F 300G P.S..A Big Word of Caution: If you find yourself electro-plating parts (cad, zinc, chrome, nickel, etc) that have high hardness (over 40C on a Rockwell scale) it is important to hydrogen embrittlement relieve the parts after plating. This entails baking the plated parts at 375 degrees F for a minimum of 3 hours. This allows the hydrogen, produced by plating, to escape "through" the plating, and eliminate future cracking/disentregation problems in the parent metal. Any steel heat treater and many platers can perform the Rockwell test. _____ From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of lettercars@xxxxxxx Sent: Sunday, November 25, 2007 5:02 PM To: tomas.turovaara@xxxxxxxxx; Chrysler300@xxxxxxxxxxxxxxx Subject: Re: [Chrysler300] 1961 300 G Hi Tomas and All: According to Chrysler drawings, most of these linkage members has optional finishes. For ALL linkage components, one of the options is "C.S.T. Pro. Std. #80". C.S.T. stands for "Chemical Surface Treatment" and Process Standard #80 is Phosphate Coating. This is what we always refered to the dark oily finish of fasteners, etc. when I was at Chrysler. It may well be the same as "Parkerizing". Eastwood calls their blackening finish "Black Oxide". That is what I used on my 300F because it gives roughly the same appearance I remember. The other options for SOME components were Cadmium Plate, P.S. #182B and Zinc Plate, P.S. #79B. SUMMARY OF FINISH OPTIONS: Bellcrank, (Assy, Intake Manifold Throttle Shaft) PN 2121745: All three Lever, Intake Manifold Throttle Shaft, PN 1947544: All Three Rod, Bellcrank to Carbuetor, PN 2128757: All Three Bracket, Accel. Pedal Return Spring, PN 2129668 (300G and late 300Fs): All three Bellcrank to Carb Adj. Link (Slotted end piece), PN 2129569: Just Cad and CST Rod from throttle bellcrank on body to intake bellcrank, PN 2121159: Just Cad and CST Assy, Accel. Shaft & Bracket (part bolted to body), PN 2121748: ONLY the CST I do not have drawings---or at least not handy---of the linkage to the transmission, but feel confident the CST finish would be appropriate. Of course, for proper restoration, one should try to duplicate what your car came with originally. In my case, I had none of the original when I bought the car, so went with the C.S.T. Phosphate (or faux phosphate) finish. The nut part numbers are not identified in the parts book, so it would be impossible to state what Chrysler specified. In this case, do your best to determine what was original on your car or consult our Reference 300F on the web site. (Of course you 300J and ram K owners don't have to worry about the above. Just paint it all Turquoise with the engine!) Whew!!! I hope this is a help, and even more I hope it is decipherable after going thru the listserver. 300ly, Gil C.

The linkage to the transmission, all of the linkage to the carbs from the firewall to the carb even the nuts on the linkage Thanks Tomas Turovaara **************************************Check out AOL's list of 2007's hottest products.
