Got a real nice 49 Cub that is just about perfect mechanically and looks real good. Has a very tiny leak that makes a wispy tiny bit of steam. Can't really see where the hole is. Might as well fix it one way or the other. Options are recore original and looks like two different aftermarket replacements, one real cheap about 8 lbs, the other near $200at 11 lbs. Recore the original I know the fan shroud will fit and the rad car will be straight. Aftermarket??? I hate paper thin fins. Has anyone used the aftermarket ones? Did the fan shroud and everything else line up ok? Fins have some meat? Cap straight? I will be using this tractor for many tasks Summer and winter. Mowing and cultivating, Snow plowing and grading.
