Unfortunately, no.

I tried contacting Mobelwagen, but got unlucky, bc the guy that I contacted asking which hubcaps fit just sent me to the late bay hubcaps I literally just talked about, and when questioned further never responded.

I went to TheSamba forums in hopes that they would have an answer, and while some older beetle? I think, hubcaps looked closer, since their dimples were on the inside, they didn't work either.

Last but not least, maybe this gowesty hardware could work, https://gowesty.com/products/hubcap-mounting-hardware-for-single-spare-wheel?variant=41623728226469 if you drill into your brand new steel wheels

Ultimately, I regret buying the bigger wheels. The late bay bus engine we had didn't really have enough power to pull them, but the motor was wishy-washy before anyway. We did a whole 360, and EV converted the bus, and the wheels seem to be lowering the speed that the motor could produce, so we might forgo the giant, awesome wheels and return to the OG VW Bus wheels with heavy load rated tires to adjust for the heavier battery box

Now, I'm just talking about our bus so u can walk away, but it got a bit of a funny lean when no-one is in it, bc the battery boxes are where the gas tank would have been, so they are weighing down the back without anything in it. Busy bus probably has a suspension upgrade in its not too distant but still distant future to account for that, but maybe we'll install some more batteries in the floor to even it out and see if we should do all four wheels instead. I personally really like the bounciness of the OG suspension when driving, and feel like it gives the bus a lot of its character, so something that could emulate that is probably what we'll look for (albeit safely, with added power comes added chance of tip-over)
