I get that alot when I tow the racecar into the pits with my motor home.
I tell them sorry; toilet doesn't work. Three different MHs over the years that had faulty toilets.
But I have been known to take a shower between heats, LOL
The only drawback is that it's the last year of the six volt Chryslers.
Although the two speed tranny that spaghetti wiring along with the brake system conversion would turn me away.
I was thinking more like a shaped piece of steel, possibly hammered in there.
Maybe even a dowel or the likes.
I am an old dirt racer, we try lots of cobbles. LOL
