I am restoring a 1949 Olds 88 Wagon. I have gotten to the rear brake drums and they are very bad. The size 11x2 with a 5x5 bolt pattern. Orielys actually had the shoes in stock, part number #228. I have seen some on ebay but I am hoping someone has had this problem and discovered that 1979 Chevy van has the same drum. Just trying to get this going. Thanks for any help
A couple of thoughts for better results. Upload some pics of what you have. Someone may have some but not know what they are. Next, please list everywhere else you have tried to call or what websites you have been to. This stops a lot of unnecessary questions from H.A.M.B. members. Good luck in your search.

Look up the other applications for your 228 shoes; then look up the drums that go with them. Look at the depth from the lip to where it seats on the flange along with the flange diameter. Bolt pattern and center register differences can be fixed.
Thanks Rich and Randy. I have looked at 228 shoe applications for drums. All pre 64 vehicles also very difficult to find. 1100 applications. The combo is trying to find 5x5 bolt pattern and accurate information. I look, think I have a match and the bolt pattern is wrong. Or its listed as a 2 inch shoe and it measures 2.5. What would be great is an original part number. Or someone has already done it. I have gone through Orielys and Napas websites and been to the stores.

Try Craig that goes by Mobileparts on the AACA forums. His phone is 516 485 1935. Seems to have a lot of NOS parts.
What I was trying to get at in my earlier post; was you don't have to limit yourself to 5 on 5 drums; the bolt pattern and register is easy to make fit. Why look only at pre '64; many cars ran 11" drum brakes up into the '80's. Also the drum width can be wider as long the depth is right. Here is a drilled to 4-1/2" drum and centering ring I used on the rear of my coupe as there were no new drums for a '57 9" rear.
I would pickup the latest copy of Hemmings and go thru it closely. Quite a few of the suppliers of NOS parts don’t use the web. I have found a few places this way that panned out well. When I’m done w my evening spin in the goat I will find a copy of Hemmings (all pre-Covid as my scrip ran out) and see if I can find anything close. Randy Sent from my iPhone using H.A.M.B.
Oldsmobiles back then had very thick brake drums. They could be turned or trued up several times in their working life. Check your repair manual and check the diameter of the drums. They may still be good if you can find someone with a brake lathe to turn them or, if not out of round or badly scored, use them as they are.
I had the same problem with a '55 Olds rear. Olds parts are very hard to find in Australia, & I needed drums for the rear of my roadster, I found 50's F100 rear drums have the same dimensions as the Olds so I re drilled the bolt pattern to suit the Olds.
A quick eBay search netted this: https://www.ebay.com/itm/Rear-Brake...49211?fits=Year:1950|Make:Oldsmobile|Model:88 Does that look correct? Maybe a wagon is different IDK. There are quite a few suppliers in Hemmings that list brake parts for your year of Olds. The first copy I found was July 2019 so I would suggest picking up a newer copy. Regards, Randy
The ones in the ebay ad are supposedly correct fitment. The originals are bumpy, for the lack of a better word. They are pretty thick so I think I will go turning them, and see how that goes. Option B is get the ones on ebay. Option C is getting some from Kanter. By the way the original part number is 413823 from the 49 Olds parts catalog. Thanks for the help lots of good info. @Bird man, that is true @Dago 88 I have not tried that. Maybe go to a machine shop? Very tight tolerances. @RICH B Nice work.
I did brakes on my 79 GMC van a couple years ago and bought drums. Turned out I didn't need them. I was thinking about my original post and that the Chevy van had 5x5 bolt pattern. It turns out the van uses 11x2 shoes also. I grabbed the drum and slowly eased it on the axle and it slid on like it was made for it!!! Dam that is cool! So for anyone whoever is reading this thread and can't find drums for there 11x2 drum with a 5x5 bolt pattern this is it. Part numbers are stamped on the drum 8819. Autozone uses that number. Oriely's uses 2065DGS and shows the same pic as Autozone with same part number 8819. Napa part number is ND 4401199. Added bonus is 59. dollars no postage, in stock, and they are finned! By the way for the safety conscious the center hub hole and studs are a perfect fit.
Also the wheel cylinders are WC4801 and WC4802 Oriely's part number. Napa could not get. Thanks Bird man. 57 Pontiac was the clue for these
