I have a 67 RT I am restoring and it would be easier to restore a different housing I have but I want to keep the car numbers correct/matching if I can. So if the housing is numbered/dated I will use it, but if not I can use another. Thanks.

I can only comment on Dana 60 rear ends...but yes 67 Dana 60 rear end is dated. On right side axle tube you should find a Bill Of Materials # (BOM) and near it one or two date codes. I believe there are two date code, one for forging date and one for assembly date. Date codes will be like 5167 A (meaning May 16, 1967 shift A) BOM# will call out gear ratio ect...Not sure about 8-3/4 sorry. I'm sure someone else will chime in.

BTT...

Mike I don't think I have evcer seen , or seen anything about , numbers being stamped in an 8 3/4 housing

It isn't stamped into the steel like a Dana, it is stamped with paint...

the axle tube stamps and the axle tube labels (commonly found under the U-Bolts?) are the only items that document a 8 3/4 rear housing is original to any one car. Rear axle housings & carriers are seldom if never frowned on when found to not be original.

Most original 8 3/4 rears will be too rusty to make out the codes anymore and their original labels are commonly corroded or MIA too. Always nice to have a good example like 1 Wild R/T's.

Mine wasn't really that nice, I tried cleaning it to be able to read it with no luck at all but I found by soaking it with WD40 the paint became easy to see & read...

Thanks guys for the responses. I guess it's worth a look to see first though.

But the 8 3/4 center case does have a raised date. Or is it a tag? I do not mean the 3.55 or 3.91 tag.

Theres a casting date (raised in the casting)& an assembly date.. The assembly date is a paint stamp

Mopar Mike,

Yes you'll need to consider if you are going to re-use the original center section. I would guess it is in reasonably good shape and no reason why you can't re-install into the non-original housing you have. As always, think about keeping the original parts somewhere close by for the next guy to decide on keeping.

Center sections are also rarely frowned on for not being original and add little to overall value even when still present. 95% of potential buyers will care less if the rear or pumpkin or both has been replaced at some point and may never ask or even question.

Rear axle housings are commonly blasted and re-painted and the codes never documented or reapplied anyways.
