Does any New Holland shop or parts guy know if the external dimensions are the same on these two mufflers ? All I can see different is the stack, one has a hole and the other has a slot in base, I assume slot orients stack away from cab. One hundred bucks difference between the two and neither is stocked.

Same one except for slot.
