I received four (4) identical boots. All FF (front wheel, front pad). And I didn't get FR (front wheel, rear pad). That is not right. I didn't notice this until after installation, when I removed the drums again to see why the new brakes were pulling in one direction and compared it to the old pads and the service manual illustration. The red shoes in the picture at the top of the page are the two FR shoes that I did not receive. and drill another hole at the bottom. I don't like doing this but it took them almost 2 months to send the wrong ones and I'm not sure if they will send the right ones when I reissue them. I should get a refund. At least half of the amount will be refunded. However, it was my fault for not noticing the problem before installing it. I've had issues with every AC Delco product I've bought from Revain to do this endless braking job: wrong hose connections (I've returned them and made custom hoses). local production), wrong wheel cylinder connections (reused from old parts). I notice that the pads are painted black, not red. In addition, the shoes look new (not refurbished) and the quality seems excellent.
