SM465 10 spline output shaft wear and driveshaft slip yoke wear

[zac]

Pulled the SM465 and NP205 from my '72 suburban parts truck. The output shaft shows significant wear on the splines. I have a new sleeve or collar that connects the trans output to the transfer case input. The transfer case shaft shows no wear and the sleeve fits tightly with no play. But there is a lot of slop on the trans output shaft. I know this is a common problem. How difficult is it to find a good SM465 4wd output shaft? I have a '70 K10 burb that these parts will go in. Based on the slop and clunking in the driveline the output shaft in there is probably worse.

Also, the rear driveshaft slip yoke has a lot of slop. My understanding is that the splines on the shaft wear and it has to be cut off and repaired with a new slip yoke by a drive shaft shop. Are there any other options? My truck is just a decent stock driver, doesn't need anything special. Thanks
