914World.com _ 914World Garage _ Shift rod boot extension- Tangerine bushing.
Posted by: peteinjp Nov 13 2022, 06:20 AM
My car has the tangerine bushing installed and while it does have a groove for the rubber boot in my case (may be related to the shift rod??) the boot just would not stay on when going into R,2, or 4. I measured the O.D. and found it conveniently to be 2.25" and ordered this 2.25 to 2.5"I.D. exhaust adapter:
A little chopping, belt sanding and then some hammer work on a simple buck yielded this:
Installed (slip fit but may do use some sealant to keep water out:)
In action:
Just thowing this out there in case others have the same problem- which I admit is unlikely but anyway....
Best!

That is a very nice solution when using the TR firewall bushing.

Jim, he says it is a slip fit, so expect that means a friction fit with possible degrees of looseness. Probably some silicone sealant would secure it and provide sealing against any water penetration.

Exactly- its just pressed onto the O.D. of the bushing carrier. I'll glue it on next time I have the car up.

Thanks- it was a fun little project. Sometimes that's the time I have for car stuff.

Great idea, I have the same situation.

I'm confused, did you have the issue before the TR bushing? It seems to me either the boot is not in spec or it wasn't put on properly. I only say this as the distance between the ring that the shift rod has is welded is a certain amount from the end of the rod which should be the same spec for any 914. That is then attached to the same fixed length spec rod going through the firewall. I'm not understanding how if all factory specs the boot would come off in 2,4,R unless the boot was never installed correctly over the firewall lip OR the boot is so worn it no longer retains the hold around the firewall flange.

He has an early car. There is no ring on the firewall to retain that boot.
The groove on my bushing carrier doesn't provide a lot of grip because the od of the carrier isn't quite large enough.
