Are the front shift rods the same diameter for side and tail shift transmissions?
My car is a '71 that was converted to a side shift transmission. I bought the Rix conversion shift bushing from 914 rubber but I can not get it to stay on place when I push the front shift rod through the firewall. It pushes the bushing out. The shift rod diameter where it passes through the firewall is .92 inches, 23.39 mm. What bushing do I need for that size front shift rod? |

if I understand correctly, you ask for what side firewall bushing you need ?
I have a late shiftrod and Late bushing (1973 sideshift) diameter of rod is 20.1mm and Late bushing inside diameter is 20.59 mm So, you do not need the late bushing, that will not fit your 23.29 mm rod. Late bushing (so wrong for you) is 914.424.224.03 Early bushing inside diameter is bigger (914.424.224.00) but I do not have an exact measurement right now. I think it is like 24-26mm. it is shown in the pic in my bushing topic http://www.914world.com/bbs2/index.php?showtopic=345742 |

For the early cars running the late shifter/trans you would need a special sized bushing at the firewall. It needs to be the early o/d size to fit into the metal section but the later i/d to fit the late tunnel shift rod. A few different places make them. You need to make sure when ordering that you get the early with late trans conv bushing.
CFR sells this one : http://www.tangerineracing.com/transmission.htm I installed one in my brothers 914 and it was pretty easy to do. Here's another. https://sierramadrecollection.com/914-914-6...-72-p32161.html 914 Rubber : https://900designs-container.zoeysite.com/r...shift-bushing-1 Check the part #'s as they are different between the rix brand. |

The rix version we have is the early car upgrade to side shift bushing. It should be the same size as the one you have to drill into the wall (Personally don't like making that kind of modification).
Why don't I ship you out the other 2 bushings (early and late) just in case some "modifications" haven't been made by a previous owner. One of the should fit. Just drop me back what you don't need. PM me your address and I will do this right now. Mark |

@ Luke,
The PO changed everything for the side shifter except the shift rod in the tunnel. That is what threw me off. The original early shift rod is still in the tunnel but everything else has been swapped for the side shifter. I bought the tangerine bearing but when that didn't fit, I ordered the rix version and that doesn't work either, that's when I started measuring the rod diameter and found it is consitant with an early rod. @Mikey , I sent you a PM, thanks!! |

[/quote] I dont know how they could do the conversion leaving the original shift rod and shifter. The original shift rod is larger in diameter. |

That's probably not an early tunnel shift rod.
It appears that they sleeved the late rod to fit the original bushing. Get the sleeve off and you might be able to use my bearing. |

I wondered about the possibility that the PO sleeved it because it just didn't look right. I'm going to try the bushings Mike is sending me on this car. I think the early should work. I swear the PO of this car must always lean to the side sitting on the toilet. Everything that has been done to this car is half-assed. Chris, I'll keep your bearing for the project car I have sitting beside the house. I will get to it after I finish this car and finish the engine rebuild on my 944 Cab. |

Also check this seat belt bolt. It maybe too long and hitting the shift rod?

[/quote] Good catch. I'll take a look and see if they are making contact. [/quote] Remember that the rod moves up and down slightly when shifting gears. It is probably the wrong lenght bolt. They are special bolts with a 7/16 fine thread. I should have the correct bolt. Or grind down that bolt. Check the other reciever bolt to see it it is the correct lenght. The other side will not inferfere with the rod. |
