There may be a bearing retainer that you can shim like a Ford pickup uses to adjust the axle endplay.

My buddy who is doing the repair at his shop is going to use Ford roller bearings. And as now as the rear end is out i asked him to do a complete go through of all the other parts. I stopped by today and he showed me that the ring and pinion gears were fine but i also could use the bearings next to the sure grip replaced as well as they were showing some wear signs.

You said it has a Crush washer ??? Do you mean thrust block ?
As far as the bearings needing to be replaced , they ALL need to be replaced and the reason is that POS cone type sure grip if that is what the car still has in it.
If he has the differential torn down have him put the solid spacer in place of the crush spacer on the pinion stem .

I don't believe that you drive your car more than on and off a trailer

John at least I drive the thing.If you have anything that runs come on down in your ride and we will go crusing.Oh by the way it was a daily driver for at least 4 years after I installed it and that was in 71.Still going strong.That and for 35 bucks I cant complain as it was drum to drum.Rocky

Almost all back together but one of the bolts in the yoke snapped off inside so it was just easier and quicker to just go by a new yoke. Hope to have it all back on the road in a few days. 
I take that back as the new pinion bearing went bad in the first few miles. So back apart again.... 
On a side note i did get an O2 sensor installed so the A / F mixture can be adjusted for optimum performance.

Ahhh... THE "Snowball" effect strikes again. I hate that. So often I start out on one thing but three other issues pop up requiring additional attention. Good luck my B body brother!

Stu IIRC you have a 489 case.Unless you replace the crush sleeve it might eat another bearing.Thats why the sell an eliminator for it.You can set up the old one but its a pain.Removing the yoke you have to get the crush sleeve almost perfect to where it was.Rocky

Tell me about the crush sleeve eliminator. I need to do a pinion seal on my 489 and have been putting it off because of the crush sleeve.

RamRod the crush eliminator dumps the crush sleeve.Its almost like it but the eliminator you can change the yoke like other rears.The rear has to come apart to change it.Dr Diff sells the eliminator.You can change the yoke with a crush sleeve.There is a explanation in factory manual on how to do it.Been years since Ive read it though.Rocky

Tell me about the crush sleeve eliminator. I need to do a pinion seal on my 489 and have been putting it off because of the crush sleeve.
A crush sleeve is a one time use collapsible spacer that helps set the pinion bearings preload.
Once you disassemble it for a new anything, a new one must be used to achieve proper preload for the pinion bearings.
A solid pinion preload spacer can be used and is better, but it must be custom installed and turned down to the exact length needed for proper pre-load.
This all needs to be done/setup with custom milled/turned pinion bearings that have oversize IDs so they slip on and off the pinion to determine pinion pre load spacer thickness. Can't use pressed fit bearing races on the pinion until you can/determine find proper pre load thickness. I have done it several times. So using and installing one(solid spacer,crush sleeve eliminator, etc) is not easy to install.
For a stock rebuild I'd use a fresh crush sleeve.
Here's what one looks like.

Stu what brand is your A/F ratio meter ? I bought the latest Innovate Motorsports MTX-L and the instruction say the sensor needs to be 24 inches behind the end of the collector to get an accurate reading .

Yes the meter was run from the sensor up through the engine compartment and out the hood. Then into the interior where you can watch it as you drive.
Right now it was reading 13.00 to 13.55 when at freeway speeds but dropped to 11 to 12 at low speed. This will again need adjusting to help the low speed ratio.
Even not perfect the car ran 10 times better already! Keep in mind i also have a way to large cam profile that i am sure is hindering any low speed performance.
