Hi folks !...new on here just bought a 1968 Delta 88 Custom with 350 rocket engine car is in amazing shape but sat for a long time , so someone decided to remove the rear yoke , just wondering if anyone might know which yoke this car would call for? or where I CAN LOOK IT UP?? ... i'm looking on Denny's drive shafts and they seem to have what i'm looking for but i want some info before I order as dealers claim they no longer have the books for these cars and can't go back that far on web vin code look ups??...so here I am??...I am in Canada if that makes a difference.https://classicoldsmobile.com/forums...ilies/wink.gif

 

Call Denny and talk to him. Nice guy and he knows drive lines. He will ask you for specific info regarding the pinion shaft in order to hook you up with the right yoke, nut, sleeve and seal. Have calipers available to take measurements. Source the pinion and seal specs. An old Motors or Chilton manual will have this. You can also look here in the classified section for someone with this rear end, or yoke in their horde. You need to know your U-Joint series too. The calipers will be needed here too to measure the cups.
Keep in mind you will need to reset the crush sleeve and pinion torque. If you dont you risk damage to the rear end. If it was me Id be disassembling all if it for a look a rebuild, and to verify proper gear mesh.

 

You may already know that the only engines offered in the 1968 Delta Custom were 455s. The 350 was only factory-installed in the lesser Delmont. Look for other "missing" items as part of that swap.

Also, be aware that you 68 Delta Custom uses the big car Type O axle with the 9.3" ring gear. That is unique to the 65-70 Olds full size cars. Most vendors have no idea what this axle is. Gevo's does offer parts for them.

 

I have a 68 Delmont. I drove it into my driveway and am dismantling for the engine. The yoke is there. Let me know.
