I am looking for a driveshaft for my 1967 442 4 speed car, it appears that some one has installed a wrong one in mine, the yoke is only 3 1/2" long and the "Yearone" book said the yoke should be 5.4" long and have external snap rings not the inside type! or any info as to where I can buy a driveshaft from?

 

I don't know anything about a "yearone" book (or why Year One is considered a reliable source of Olds parts info). I do know that the factory parts book shows that your car uses u-joints P/N 5677659, which have INSIDE snap rings. The front yoke for your car is shown as P/N 5695103, which was used 1964-68 on MT and Jetaway transmissions except the Dearborn HD three speed.

 

man 5 1/2 inches long,that sounds almost like a long tail shaft yolk.

 

The length of the tailshaft has nothing to do with the length of the yoke.

 

I don't think you are measuring the yoke correctly. You need to measure center-line to the end.
I just checked the yoke I have from a jetaway transmission , as Joe said same as the one you need
it's 5 1/2 from the center-line of the u joint bearing to the end of the yoke and 3 1/2 of machined surface to slide in the transmission.

 

my yoke measures the same 3 1/2" but only 5" to center of bearing! my assembly manual says that drive shaft should be 59.10 center to center but my drive shaft measures 60 3/16"..I also have a M20 4 speed and not a jetway trans

 

the new yoke I got from yearone is 5 1/2" from center to end of yoke but it has external snap rings! I am still unsure about how long driveshaft should be for 4 speed trans!

 

Jetaway and four speed are the same length and use the same length driveshaft.

 

The chassis service manual list the drive shaft as 59.10, matching what you found in the assembly manual.
The yoke in 67 was used for auto and manual trans had a Saginaw / 3r u joint, internal snap ring. Unless I am mistaken any stock drive shaft is going to be set up to use the internal snap ring u joint.
What series u joint does the new yoke use? 1310,1350?
I may have a drive shaft the correct length, I will check and let you know, only thing is I am sure it uses the internal snap ring u joint.
where are you located?

 

Like Cliff Ruggles is with Q-Jets, Denny knows driveshafts. Call him. He is the authority.

I live in Cadillac Mi. Do you have any idea what my drive shaft came out of?(60 3/16) the new yoke has the external snap ring but I will just buy the internal one's and I hope Yearone takes these back! buy the way I meant service manual not assembly

 

The 4 speed driveshaft in my 67 442 is 61.5 inches long from end to end or ear to ear, not measuring the yoke.... the 4 speed driveshaft should be continuous steel with no rubber connection in the tube.

 

mine is 61 3/4 measuring that way! my car has a 1969 350 in it at the moment and I should be getting my 400 back from engine builder soon to put back in the car, is there a difference in the length of the 350 and the 400 engine? the service manual said the length of the shaft from C/L on bearings should be 59.10", that means my shaft would be a little over 1" to long (61 3/16") and yoke is only 5" from C/L of bearing to end of yoke not 5 1/2"

 

The engine has no effect on the driveshaft length. The trans is in the same place either way. The rear axle DOES effect driveshaft length, however. The Type O axle has a different length from the pinion flange to the axle shaft centerline than the BOP 8.2 or other GM axles. Which axle you have will change the driveshaft length.

 

My rear is a P type 10 bolt cover, is your driveshaft a solid 1 piece tube?

 

mine is the type "P" rear axle with 3.55 posi

 

it appears t be solid and steps down once in front and steps down twice in the rear, the tube gets smaller front and rear

 

That appears to be a concentric shaft from an AT car, with the rubber between the inner and outer tubes at the back end.

 

So the picture shows a non stick driveshaft. If your car is factory 4speed then yes someone swapped it but your length should be fine with the proper yoke.

 

it is a M20 4 speed car! you really think that the drive will work even that it is over an 1" longer than the service manual call's for?

 

One more time, which axle do you have? The Type O axle requires a driveshaft about 1" different in length from the one for other axles. In any case, if you can unbolt the rear u-joint and slide the yoke into the trans by at least 3/4", you'll be fine.

 

thank you for all your info and time! I will have wait until I put 400 and tranny in to find out.

 

Your car has a P type rear as mine does, I have the correct driveshaft in mine at 61.5 inches ear to ear. You say yours is 1/4 inch longer than mine....I don't see an issue.
