I have a '66 427 roadster with reproduction knock-off's that are approximately 20 years old. (The car has had less than a thousand miles in the last 20 years). The problem is, the "safety" pins will not stay in. I am using hardened "roll pins" that are so tight that I have to tap them in the hole with a hammer. I tried ordering solid pins from Paddock - but they are smaller than the hole. Should I try Loctite? Some other type pins? I am afraid it is a matter of time until one of the wheels comes off.
