Seat from car, tractor, digger etc (Abertillery NP13)

I'm fixing up an old digger and am looking for a seat for it. As you can see from the photo the existing seat was in a dreadful condition so pretty much anything would be an improvement. I regularly pass through Abergavenny, Usk, Monmouth, Pontypool and Cwmbran so don't worry if you aren't on my doorstep. Thanks 👍
