Hi Larry, I have the exact wheels for my 48’ and I have the exact same issue. Mine hits on the rounded edge on the inside of the wheel just like yours. I have contemplated removing the rear axles to have longer studs pressed in, (and on the front as well) but then decided to look for the proper rims. Well neither solution is cheap or easy so I’ve moved on to other issues that need addressing hoping that some rims would fall into my lap while part searching for other issues. Anyway please post what LMC says as I am very interested as well.
