i imported cabs in ukcabs are rare in the uk have been for sometime as no one imports anymore!
Thanks for heads up,appreciatedI can't help with the pcb, but as long as you don't own it already, at this rate you might just want to consider the Xbox360 Muchi Muchi Pork & Pink Sweets release , a JPN/Region free 360 and one of these 360 --> jamma adapters ( https://www.aliexpress.com/item/1005002539526156.html?gatewayAdapt=4itemAdapt ) no idea what they're like though so it's all a lottery regardless.
good luck. hope you find some way of getting it.
How times have changed!They have gone up quite a bit, I sold one for £500 a few years ago.
