So,
I riveted the firewall bushing in.
I made the cup bushing taller to overcome the fact that it no longer snaps on, it just sits there and the ball slides in and out of the bushing.
the one on the transmission I bought from PP.

I was able to make the tolerances much closer, used waterproof grease, and it shifts nice and solid now.

Nice work, is that brass ? I can't tell from the photos. Does your camera have a "macro" button?

Petrified Squirrel Meat???

If you used an Oilite bushing, no extra grease would be needed........

What is the difference?

Bronze has a higher nickle content than brass and that makes it more durable.

Correct me if I am wrong. (IMG:style_emoticons/default/pray.gif)

They certainly are cool looking. Let me be devil's advocate for a second:

Wasn't the idea of making them out of plastic so that the plastic would wear before them metal did? Will the metal cause additional wear on the shift linkage?

Bronze is a copper and tin alloy. The high copper content makes it more corrosion resistant than brass. It is also harder and stronger than copper. Bronze can be made to be porous, which holds the oil in the bushing/bearing making for it "self-lubricating" or "oil-retaining".

Brass is an alloy of copper and zinc. (2/3rds copper 1/3rd zinc normally)

Either can contain other metals, bronze bushings often have silicon in them for instance.

.tim

PS: yes, the bushing should always be designed to wear before the linkage. But brass should in fact wear quicker then the steel linkage. Although not as fast (or as low friction) as with a plastic.

well,
Steel is harder than brass.
I rounded the edges inlet and outlet where needed to ensure smooth travel and no uneeded wear on the rod.
And the tolerances were terrible when I bought a new set of plastic bushings.
I made these alot tighter, one one thousandth's of an inch for grease only.

I looked into using graphite impregnated bronze, but it was to costly to buy the stock, and a friend had the spare bronze, so that made the decision.
