| | | | Joined: Dec 2008 Posts: 67 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2008 Posts: 67 | I am trying to change the transmission I have in my 49 chevy truck into an open drive. Right now I have a 4 speed torque tube trans. I was given a two piece drive shaft with a carrier bearing. I would like to change the rear of my 4 speed trans to except the open drive. I have a choice, either change the trans to a T5 S10 trans or stay with the original 4 speed. I'm trying to get the S10 trans rebuilt but I think I wouldn't mind staying with the original 4 speed if I can get the drive to work. Can anybody help with pictures or info ?

Is the truck a 1/2 ton? I would go for a one piece drive shaft, if possible, and avoid the issues of a carrier bearing.

My 54 1/2 ton has an opend drive line with a 235 and 1955 three speed o/d trans and 1965 1/2 ton rear end. If you like we could meet half way and you could take photos.

thanks
Is the 3 speed O/D the same as the 4 on the floor I have? I'm at the 91 and the 15. | | | | | Joined: Jan 2009 Posts: 106 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2009 Posts: 106 | Sounds like you C notched the frame to lower the rear end? I am not sure about that set up with a Nissan rear. You could call Tom at Foreign and Chevy Truck Salvage in Santa Ana who knows everything about trans and rear ends in old Chevy trucks. The 1955 Chevy 3 speed o/d trans bolts up to the bell housing and has the open drive splined shaft at the rear of the trans. I am going to Pomona Swap Meet on Sunday and could take the truck if you want to see it there.
