r4

asked this a while back but I need a starter and fly wheel for my r4 what other dozers might get it out of for this dozer

I am fairly sure that R2 and Maybe 22 starters fit , But I am away from Home at Present and won't be back for 8-9 days to check my books , Ring gear Maybe D4 same vintage ??? that I can also check . I am going to convert one Myself soon ,I have both flywheel and starter. Someone else may have Books to Check for You .
