injector is a bosch

KDEL 65S1/13

I need to know what 'size' that injector is.

Long story:

I have a JD 790D excavator with a blown head. Head is an R61521 ( crosses with a JD 4840, 4640 and 4440 plus many others )

I can find a few reman'd ( and welded ) heads for sale, but hit a snag.. at least a couple of the selelrs say there are 3 possible injector hole sizes.

Anyone know what size this injector is?

thanks
