Re: 1969 Camaro RS Z/28 - "Brooklyn Project"

I'm attempting to re-seal the diff cover so I bought a new gasket and used Permatex gasket sealer which I've had success with in the past. I know its not the preferred way to go as the better approach is to eliminate the gasket all together and instead use modern RTV which is more effective - its just not the way the factory did it. Sooo...I thoroughly cleaned the sealing surfaces and applied a thin coat of sealer to the cover and diff, allowed it to nearly dry per the directions then installed the new gasket and torqued the bolts to 20ftlbs in a cross pattern. I re-filled the diff after filtering the gear oil and rotated the assembly several times to agitate and distribute the oil. Now its a waiting game. After several hours, no leaks to report however I'm going to leave the assembly for about a week to verify its not leaking then repaint.

Not much to see here, its just satisfying when an assembly finally comes together. The restored wheel and hub with a 413 Dill valve stem (thanks Chick), cap and restored waffle pattern lug nuts.

Thanks Chick, I have a nice NOS idler arm I was thinking of using to save some time, its an early NOS piece with the same PN# however I discovered the rotating arm is "thicker" than the original so that wouldn't do. Fortunately the original was solid and restoreable.

Re: 1969 Camaro RS Z/28 - "Brooklyn Project"

I have several small parts that need zinc or cadmium plating and commercial electroplaters aren't fond of them because they are finicky, labor intensive, they generally need to be individually wired and they sometimes get misplaced (it happened to me). We decided instead to set up our own in-house plating station for clear (silver) zinc, silver cadmium and zinc dichromate (gold zinc). The setup does take some time, effort, expense and involves equipment and attention to the process. The equipment includes a plating tank, rectifier (power source - we chose a 10amp in case we want to do other finishes in future), copper hanger bars and wire, a 300w heater, agitator / filter (aquarium type), thermometer, plating grade anodes, acids and plating solutions. If you want to do zinc dichromate you're messing with sulfuric acid so care is required. After sourcing the materials and solutions I assembled the station and tested a shifter part that had been vapor blasted. After adjusting the amperage a couple of times the result was on target. Next will be the zinc dichromate station that I'll set up and test in a couple of days, followed by clear zinc.



Test subject - cadmium plated shifter part (right), bare steel (left)
