Coolant expansion tank replacement (part number needed)

[BeefyBalls]

Driving to work this morning and thought a sniper was taking a potshot at me, heard an almighty POP. Upon inspection found the coolant tank screw on cap on the other side of my engine bay and my coolant below Min mark. Went out and bought a replacement cap as the old one had split and also refilled with coolant to the Max mark. Drove home after work only to find it was at the Min mark again. Upon further inspection have found a small crack at the rear of the coolant tank hence needing a replacement. Is this an easy swap or is it a pain in the ass job??

If any of you wonderful peeps on here could link me up to one off ebay, eurocarparts etc I would be eternally grateful.

Seems to be one problem after another since I purchased this 28k 1.6THP 156 in April.

Love the RCZ but have spent more on this than I ever did with my 2016 Nismo RS before my lovely Missus wrote it off.

btw, according to Service box its a 30 min job. Refilling and bleeding the cooling system is also required but I'm sure someones done a "HowTo" on here.
