The zx 71B five speed does not have a Roadster front case to swap on. Closest is one from an SD22/25 from a 720, even has the starter on the correct side. You would have to mix 'n match the throw out bearing collar to the Roadster PP and flywheel. It's been done but not a drop in. My '85 SD25 front case... Cut off front from Roadster transmission... Scary close. 1 Quote Link to comment

The starter is on the passenger side. Yes an L series front bell was made so the Roadster 5 speed could be used on the early 240z. Note the starter is on the correct, right side. It was available through Nissan, probably NISMO. I heard (may be true) that they were optionally available on Z cars in Europe but you could import the bell. 1 Quote Link to comment
datzenmike Posted December 17, 2023 Report Share Posted December 17, 2023 Looks exactly like the '74 710 which looks exactly like the 510... Angled pads and all? Quote Link to comment
KELMO Posted December 17, 2023 Report Share Posted December 17, 2023 Yes, the SSS 411 pads are just like the 510, angled and all. At least on mine they are and those calipers look the same. Quote Link to comment

As a matter of fact you have to order 510 pads since no index today carries the RL411 as a valid entry, Ask me how I know. 1 Quote Link to comment
datzenmike Posted December 17, 2023 Report Share Posted December 17, 2023 I think the first year '73 610 also had this. After they went to larger engines and the 6110 and 710 were heavier anyway that the 510. The 610/710 switched to different caliper and larger pade for use with the L20B.. 0 Quote Link to comment
Greaser2 Posted December 19, 2023 Author Report Share Posted December 19, 2023 I guess I was stunned when the 5 speed shifter lines up nearly perfectly. Was expecting to do some metal work. Neutral position. 3 Quote Link to comment

iceman510 Posted January 19 Report Share Posted January 19 Same question, and what produces the yellow zinc? I have seen silver zinc but not usually yellow done at home. Quote Link to comment
Greaser2 Posted January 19 Author Report Share Posted January 19 It is the Copy Cad Zinc Plate from Caswell. Then buy the yellow chromate to make the yellow color. I also did some in Blue(Silver/clear) Chromate. You can be very limited by the size of the piece. Caswell is not quick to tell you the limitations and thus the costs start pilling up and get expensive so hard to justify for just one project. 4 Quote Link to comment

iceman510 Posted February 5 Report Share Posted February 5 Looking good on the parts. Another question on the plating- I had some done and it did not turn out as shiny as I would have liked. I think I just glass beaded most of mine. What do you do for preparation? Steel wool? Wire brush? Something else? Thanks. Quote Link to comment
Greaser2 Posted February 5 Author Report Share Posted February 5 (edited) So no blasting is needed. Clean any oil or grease with Gas or solvent soak. I don't have a blaster so I do a wire brush next to clean anything else remaining, dirt and rust. Pitting will require blasting or I grind the pits out. Immediately after a Muriatic Acid soak (removes old plating), I will wire brush to get the shine. I will Copy Cad within the same day else the shine starts to fade. If it's not shiny now, it likely wont be so wire brush is the key for my prep process. There is some technique for shine in the Copy Cad process. Using brightener every couple hours, low amps will make it dull, when you pull the part out of the zinc bath, it should be mostly shiny, similar to stainless steel, followed by a 4 second dip in 5% muriatic acid should really make in shine (you can see it pop) else the zinc plate was not good. I didn't invent this process, I mimicked Mikes process mostly, most people have seen this. There are many bad videos out there too. Although he does do blasting. Part 1 is his Prep process. Also, you can compare my Zinc chromate to Ztherapy's, mine is much brighter. This may be due to poor plating or prep or light use of yellow chromate in the Chromate soak. I doubled up on the yellow chromate from what Caswell recommends. I believe Mike below quadrupled the yellow. If you are seeing very shiny parts going into the yellow bath but pale yellow coming out. Up the yellow. Edited February 5 by Greaser2 1 Quote Link to comment
