Drive shaft question

[Baz]

I am in the final stages of converting from Auto to 5 speed. There is a support bracket that bolts on to the plummer block bearing (drive shaft) and fixes to the bottom of the car body. It would appear that where it bolts to the body there should be some kind of bush that seats in the bracket and the bolt goes through that. I wonder if I need that bush as the bearing does float in the plummer block, and maybe I can just bolt the bracket up without the bush. Can any one help ??

Baz,

The bearing is pressed into the pillow block using the outer race of the bearing, then the bearing is pressed on to the driveshaft using the inner race of the bearing. Then install the yoke fitting and the nut. The pillow block is bolted to the bracket, there should be a spacer/washer between the pillow block mount and the bracket.

On a 5 speed body there is two sets of studs that drop down through the floor pans, I don't know if the auto body has those studs. You'll have to assemble everything to get the proper location of the studs before drilling holes through the floor pans.

There should be a rubber bushing and a metal spacer that fits into the hole in the bracket. Similar to the radiator mounts.

the center support and mount bolt to the body in the same place on manual and automatic cars. It's only the front piece of the driveshaft that is a different length. There should be studs mounted to the floor for the support crossmember. If the studs are missing, they may have broken or stripped and been replaced with a bolt through the floor. The support crossmember does use a rubber bushing and spacer. I've seen lots of them bolted directly to the floor without the bushing and spacer though.

Thanks men for your input, I have the studs on the body, and am ready to bolt drive shaft , bearing block etc up, I have been unable to locate the support bush and rubber bush for this bracket. I will have to go ahead without them and bolt all straight to the body, using some big washers, maybe a rubber block on each side to avoide any vibration to the body. What do you think ??
Thanks in advance..

the rubber bushing is very thin, it's similar to the radiator bushing as stated before

I originally bolted the bracket on my car directly to the floor. Then I happened to be looking through the "Help" cards at a local auto parts store. There is a card containing 3 rubber bushings that fit not only the bracket but also the correct bolt diameter. Cost about $2. It is for Gm windshield wiper motors. My parts drawing didn't show a little spacer in the center of the rubber so I didn't use one. Could be my imagination but I think the car is slightly quieter with the bushings installed. They have only been on the car for about 1000 miles so I can't say how long they will last.
