I don't think he was criticizing. He was just pointing out that there was an error.
When I first saw that Wilwood came out with their disc kit for the 8 3/4, I wrote them and asked if it would just bolt onto an 8 1/4 without the centre bolt. They said no, it wasn't that easy and wouldn't bolt on. I never did try it even though I bought a kit for an 8 3/4 and I have a spare 8 1/4.
Dam I should get my *** out there and try it for you guys.
