Wow!! That thread is over ten years old. With everything available over the counter now, what is advantage of fabricating it yourself? I am jealous of such skills and equipment, but it would be interesting to feel a side by side comparison. Maybe a future WCR or other event.

I’ve never read that thread but Dave has taken me through a lot of the special features of his car. Any one of them blow me away. For instance, not realizing the 914-6 used a longer wire to the heat flapper boxes, they came up short. So Dave machined some extender brackets out of titanium to make up the difference. And then there’s the custom made fire suppression system. It’s all really amazing. @914Dave

I never saw that thread before tonight.
I purchased the Bott kit in 2013 and worked on the trans, shift linkage and clutch
linkage while doing my GT project.
I had contact with Dave over the years but had no idea he was fabricating his own
shift tower. Among other great feats.
My set-up uses all stock parts except for the shift rod below the engine.
I shifts OK but could certainly be better.
I'm hoping that when I get back to it I can make it smoother and decrease the
throw.
Fantastic work Dave. Beautiful.
Can't believe it's been almost ten years.

I ran into the same problem early on with my 914-6 factory heat exchangers. Bug pack/Empi sells short throttle cable extenders that work perfect for this application.
914 rubber also sells the correct length cables.

So, How do you "flip" the ring gear ?? Do you replace the pinion shaft (gear) ??

No need to replace any of the major parts. You literally pull out the pinion shaft, grab the ring gear and associated bits, and run them around so they are on the other side of the pinion gear. In the pic I posted, just imagine the "differential carrier/ring gear" part flipped around so that what was toward the top of the image is now toward the bottom of the image, and what was toward the bottom of the image is now toward the top.

Of course, there has to be room for the assembly on the other side of the housing that it lives in. And that's where some of the work comes in, because some trans designs don't really have room for it that way.

lots of info

I cant believe its been ten years since i did the trans work. I will say that the shifter and trans operate smooth and reliable. I have around 17K on the setup now. Worth the effort. I was fortunate enough to find a Vellios kit cheap and by dumb luck. That made the decision easy to forward with the 915.

Hey DD. THANKS... this is helping me understand.
So... the ring gear + diff + bearings are "symmetrical" from the pinion centerline??
would any brand LSD work ??
