Hi -
I posed the question to the Goodall Design website. Received a response yesterday from Brett:

Hi,
There is not a "factory" solution for this... In fact you are the first person to mention this.
If it is something you would like to fix, I would suggest drilling out your current holes and then having some liners machined from a high tensile polymer (bearing plastic) and pushed into the casting.
Although it is conceptually very simple, the tolerances are pretty small, so I'd suggest having a professional do the work.
Thanks for the feedback, this is something we will add to our list of improvement we can make to future models.
Cheers

I think my tentative plan at the moment is to see if I can find something off the shelf that would match the OD of the Pintles and then have a machine shop drill out the castings and press the liners/bushings in.
