you will need a drive shaft with center bearing

ok where would i get one at? and where do i mount the center bearing i have a short bed and the drive shaft i have is all 1 piece!

you have a few other considerations also. the 465 frt brg retainer is larger than the trans you now have. you either have to have the hole enlarged in your b/housing or put in the later b/housing which doesn't bolt to the c/member. you will thn have to install a rear trans mounting c/member

On a shortbed you don't use a carrier bearing. What you will need is a one piece driveshaft that has a slip joint on the trans end. Then the U-joint will bolt up to the yoke on the back of the SM465. In your case you will have to either find a used one in a wrecking yard, or private party, or have a new one made. If you can find one that is too long and have it shortened, that will be less money.

Glad you mentioned that Ron. Yes he will have to change the bellhousing. However all he needs is a '68-'72 bellhousing. They came with the SM465 and still mounted to a crossmember. I happen to have 2 or 3 laying around.

Yes I would sell a bellhousing. I would like $40.00 plus shipping. Send me a PM if you are interested.

For a driveshaft, one from a '63-'87 shortbed truck with a 4 speed should either bolt up or be workable.
