A trailer hitch project for my 49 3100 is in my future too.
I want to pull a trailer of small antique tractors to local shows.
I can't remember where I saw it (and I'm searching back) but someone made a hitch bracket out of angle iron that bolted to the frame rails around the spare tire carrier (keeping it usable) and the reciever hitch exited through a square hole cut in the bumper.
Probably real similar to whats been already stated in this thread.
No other input, just subscribing & watching.
