P38 rear seatblet buckles

I've been looking for a full set of rear seat belt buckles/receivers for my P38, as previous owners dogs/kids have knacked mine. Does anyone have any ideas for finding some, or have some they want to shift, as all the 4x4/landrover breakers don't seem interested in selling them. There's loads of seat belts on offer on fleabay, but they don't include the receivers, or sell them seperately???

PM Dantheman 4/6 he breaks them.

Cheers Irish, I'll give him a bell.
