OK, OK! Since I don't have the original measurements I've used to make my jig, which was longer ago than I remember, more like 10 yrs. If I remember correctly there's about 1 1/8" offset from the shifter bushing boss in the firewall to the console on the transmission. So YES, you do want bends in the shift rod to account for this offset. If you don't have bends in it, the firewall bushing acts like a fulcrum and forces the linkage over to the side, and makes it harder to engage the reverse/1st gate.

Looking at my original 914-6 and the 74 6 conversion, both with later
side shifter transmissions and stock original heat exchangers, the shift rod has to be straightened with this combination of parts, because the heater section of the 914-6 reaches right up under the oill return tubes. This makes it necessary to run the shift rod on top of the heat exchanger. On the other hand if your exhaust system does not reach into this area and when attached to the engine you have a clear view/path from the exit on the firewall to the shift point, rebending is not necessary.

My shifter rod had a bend around 150 mm from the end of the gearbox shifting was ok then worse ,I know my 911 mounts are shit and have gone soft,removed the rod and the end literally fell of due to a crappy brazed weld.
New mounts on the way and plan to deal to the rod,don't think my gearbox can handle to many more bad shifts (IMG:style_emoticons/default/sad.gif) (IMG:style_emoticons/default/sad.gif) . Maybe I will pm Perry for his master plan?,I don't think straight is right for a sideshifter. |

I believe it is straight but optimally will need a second joint in the back to eliminate any binding as it enters the shift console.
Take a look at the tangerine shift kit. |

I know you are talking side shifter..
but here is an original 6 tail shift rod that was cut to use in a car with an early 1965 engine. Pretty serious mod, but it shifted fine.  |

Holy thread necromancer!
(IMG:style_emoticons/default/blink.gif) Also, whatever you do, just make sure the start and end of the rod are in the same plane. If they aren't you'll get binding ... (IMG:style_emoticons/default/shades.gif) |

I didn't have to modify mine at all. 75 914, Rick Johnson mount, 3.2l, stock 901 side shift.

Have a 73 side-shift car with a 2.2 six.
John Holleran, who did the conversion and has done a dozen or so, mentioned he built the shift rod by using the forward shaft from a 911 (the one that goes into the interior) and the back of a 914 shift rod. It looks straight to these eyes, and the welding is beautiful. I was worried about the shifting, as my 914 was one of the better shifting 901s I had tried (or more likely just familiar). It shifts better now than it did. YMMV! |

stock bend...non-modified from my 75...shifts perfect with no interference with heat exchangers.

I'm still working on my conversion and this has been in the back of my mine...I'm going to build a jig. Does anyone has a extra side shifting rod I can cut up to help the process, will pay shipping. If so, and you like the end results I will modify yours at no charge. Best, Mark

This is what I did.
It's an assembly of four pieces. I used the front and rear of a side shift rod with a length of rear shift grafted into the middle. Done in a fabed' jig. This is for a 6 conversion with stock heat exchangers. I used the curved sections of the rear shift rod to create an offset to clear the HEs. I'll do the same for the 915 installation which has a 916 replica side shift mechanism. Attached thumbnail(s)
