I’m wondering what the correct length is for a 1968 GS 400 speedometer cable. I’m replacing mine and it’s about 56”. It’s a screw in on both sides. Not seeing that length online. I don’t want to go too long.
Hey Matt... I used these guys with most excellent results. I believe the guy is BRYAN and is prompt and knowledgeable on the lengths. We conversed several times; tell him I sent you LOL. He'll probably remember me! https://www.ebay.com/itm/Speedomete...riorityMailPaddedFlatRateEnvelope!54241!US!-1 I had to swap trans sides from a 3 speed manual to a BW T-10 on the passenger side drive. That was through the original route, clamped to the bottom two trans bolts, and looped around above the crossmember into the trans. Im pretty sure mine was 83" long. The OEM 3 speed (drivers side) should be the same as a 350/400T. The 3 speed was 49 inches. Heres two posts of mine from 65GS.com: I pulled the 49 inch speedo cable out. Ive seen a bunch for sale at 68 inches, but that seems short to get to the 4 speeds' passenger side to attach. The dash end has a nut thats 9/16" and the trans end is 3/4" BTW. Of Course my cable looks like new. So now I need some sage advice. The super T-10 thats going in has the speedo drive on the passenger side. The OEM 3 speed manual was on the drivers side, and the cable was 49 inches. Woefully too short. JC on V8 ran into this as well. Bought one thats 70 inches an "kinda tight" for his 1970 455 X 4 GS. I just found one by chance in either 73 or 83 inches. My choice on the length. I dont want to snake it all over by the hot pipes. Any suggestions? The new one is a perfect fit (connector wise) and dead quiet. Good luck with the install! The worst part was getting through the floor,jute,rug and pulling the plastic toe kick plate and gas pedal stuff outa the way. ws
Perfect, thanks Bill! His price is a little higher but the connectors look better to me than some of the others.
You can probably save a few bucks, but his communication was spot on! We exchanged a few PMs with pics etc. He really liked the pics of the BLASTER project! An honest car guy thats not just some chinaware warehouse! ws
Ok thanks. Doing the project once with a quality part and reputable person is worth a little extra. Besides, how will I ever get upside down on this car if I use really cheap parts? Lol.
I think that I can give you the factory length but I need to know if the trans is auto or manual. For reference the Buick part group number is 4.342.
The cable with the casing is 57" if it does not have cruise control. If it has cruse it would be 52".
Thanks! That’s perfect. No cruise, so my measurement of 56” wasn’t too far off! Probably the original cable.
So I’m a little ignorant about a Buick group number. I know what a part number is but not a group number.
A group number aggregates the type of part, and closely related parts, by year, model, how the vehicle is equipped and part numbers. For example, for this part the same group number may also be used to reference part numbers for just the cable without the casing. Think of it as a Dewey Decimal system for parts.
Stopped in at NAPA to get my NAPAgold 1258 filter. They just happened to have a 63” cable in stock. $10. It looks alright so I’m going with that.
