This isn't exactly the right section for this thread, but there doesn't appear to be a section for the exterior step. I recently purchased a 71 1400. It came with a home made step under the door but the seller have me what he said was the original sliding Shasta step that goes on the trailer. I painted it and went to install it, but I'd does not appear to be wide enough to be able to bolt up to the metal joists under the trailer. It is like an inch two narrow. Cannot see how that thing goes in there. Any ideas?
