A Stupid SM465 Question
Say a fellow had a few SM465 transmissions in his private parts stash. Say this same fellow wanted to put one in a short bed truck with a 1 piece driveshaft....
Is there a slip yoke for these transmissions? They all have bolt on yokes right now, for a multi piece driveshaft with slip coupling in the middle. I am wanting to use a slip yoke so I can retain a 1 piece shaft in this truck. Can it be done?

Re: A Stupid SM465 Question
i have no ideal about the slip yoke for tha trans but you could have a drive shaft made with the slip part in the drive shaft itself you know like the 4x4s use

Re: A Stupid SM465 Question
I've never heard of a slip yolk for an SM465. Not to say it doens't exist, but I doubt it

#26 on the side index of parts lists the spline and shaft diameters or the three output shafts that SM465s came with. The 2wd version of SM465s came in GM trucks somewhere from ~'73 to ~87. Did 2wd GM trucks ever use splined driveshafts?

I just didn't word it that way because I was clumsily trying to say that since we know that 67-72 2wd GM trucks didn't come with slip yoke'd SM465s, maybe some of the 73up 2wd GM trucks had slip yokes. Especially the later '78up 2wd model SM465s that had 32 spline output shafts. I think the 32-spline output shafts stuck out further than the 10-spline & 35-spline output shafts. Of course, we know for sure that no slip yoke would ever have been made for the 10-spline units. ![]() ![]() Novak mentions the 68-91 year run on the page before the parts page I linked: http://www.novak-adapt.com/knowledge/sm465.htm Good catch on my poor wording, though. *Knowledge* is good. ![]()

Re: A Stupid SM465 Question
TxFf, if you get stuck on this, knowledge wise, perhaps a driveshaft shop would have info on the dimensions and spline count of available slip yokes that you could match to the Novak #26 output shaft info. Slip yokes are common spicer parts, no doubt. Maybe they know or their books have the info.

Re: A Stupid SM465 Question
Call your local driveline guys and let them set you up!! I have Jeeps and this is a no-brainer for a good driveline shop.

Re: A Stupid SM465 Question
Never seen anything but a fixed yoke on the back of a 465, reason being, when you tighten the bolt/nut that holds the yoke on, it 'clamps' the rear output bearing tight thus locking the mainshaft in place. On the 4wd model there is a big nut with a lock/fold over washer that accomplishes the same thing.

Re: A Stupid SM465 Question
4x4 used 10 spline 68-79. 4x4 used 32 spline 80-up. 2WD used 35 spline 68-up solid yoke.

Re: A Stupid SM465 Question
Thanks for everyone's input on this.
The reason I was asking is that I'm putting a beater short bed truck together and trying to get it completely done for under 1000 bucks cash outlay. I had 2 SM465's, so I figured to try and use one of them. But, in the meantime, I traded some welding work for a good Saginaw 3 speed. A 3 speed isn't sexy, but cash wise, it is free. So, the SM465's will be used on somethig else, later down the road. Again, thanks for all the help here fellows. Kevin
