    It's hard to find the exact OEM Number but I narrowed down that I need (Please confirm if these numbers are match for the XJ 400 SE)

    OEM:     ~4G0-11610-00
    Aftermarket:     11-Y4G0PR

    I am from Macedonia so it's almost impossible to find OEM parts. Can anyone more experience confirm if the aftermarket parts would do the job or anything else I can use inst4ead? Thank you in advance

    Update: Messured the bore with the Vernier caliper, it was reading 50mm(not sure if I read id right since I couldn't find anything about 50mm pistons). Ordered the 51mm 11-Y4G0PR from cruzinimage. Honed the bores, redid the valves, main bearings looking good. I will use headgasket from XJ550, need to wait 2-3 weeks for the piston rings to arrive.
