You can convert your early Posi over to a late Posi cover and 9 bolt ring gear ( much Stronger) by machining the late bearing hub flush with the side bearing.Then transfer punch the 7 bolt holes that don’t line up with the early carrier and you in business. That’s what’s in my early racer

I just need the stronger 6 bolt early aftermarket cover. I have an assembled early 4 spider with 4 spider gears. Just need the cover.
Need the 4 spider gears for another project.
Thank you for your comments.

Do you have the GM part number of the gears that you are looking for? I am relatively sure of the item, but I have a lot of spider gears from other Chevrolet models in the boxes, so a part number will make looking easier.

If I remember correctly, both the 6-bolt and the 9-bolt patterns are drilled in the aftermarket covers for early and late diffs. If you find a cover for late models, do as Mike Levine recommended and simply remove the excess length on the bearing hub so it can be used with your early carrier.

Not sure if this will help. Was ready to bolt up, when I decided, go this deep for a four spider Metcalf build, might as well get the billet cover. May have gotten Clark's last one. It IS a late model. I'd like $150, shipping included for lower 48.
