Thanks..You are a fountain of knowledge!..I have a Silvia box on my red 240, but I don't like the thick shift at the base and want to have what I did in my 1st Zed back in the 80's. There is something nostalgic about this shifter shape. Before you tell me, I know, I need to re fabricate to fit Silvia box, happy to do that..Perhaps I shoudl be looking at a S14 shifter that suits with a similar shape?..Any leads out there?

 

Just want to get rid of that stubby base and ad a little length...I know its lurking there under my leather shroud which incidentally doesn't sit right with that much meat at base. Yet another 1st world problem to overcome :)

Send me your shifter & I'll hotrod it for you ;)

You need a donor shifter stick from any B type box.

Hard bit is seperating the big diam rubber insulated shifter from its stub, on the s13/rb type boxes.

 

Once done, drill a short hole into center of the sr/rb stub, then measure the length f the B stick in comparison, at the stub of the rb/sr, cut the old style stick, then machine the cut end ( lathe) into a spigot, that is a reasonable push fit into the hole in end of stub.

Bit f chamfering, and eitheer silver solder, or tig up the joint

Clean up, reshape new grafted stick, done.

The male spigot/female hole, gives that little bit more strength and support, compared to a pure chamfered butt weld.

I don't agree with that Jason.

 

A small dia. press fitted spigot in an already small dia. shaft will not have any real benefit over a joint that's been beveled and CORRECTLY welded.

What you are inducing with a spigoted end fit, is a point inside the shaft that is not permanently locked together (even after welding the outside) that can eventually create a

fisher crack from the inside-out, due to flex in the shaft from shifting.

 

Simply by cutting a generous chamfer into the shaft, welding it with the TIG so as to get full penetration to the core of the shaft with a generous weld pool,

is more that enough to give the shifter adequate strength.

I've performed that modification numerous times now without a failure - including my own Zed.

 

It's a really neat, simple conversion that has a dramatic effect on the way Zed drives :)
