I have a stamping on two of my mufflers,
H4L301, and H0L301.
Being a later 29 and late 30 they should take the same muffler.
Anyone know what these numbers mean?

I've got one marked H7F301 that I bought from at a swap meet some years ago. The seller had a small pile of them and mentioned that he bought them from Midas Muffler on a close-out sale about the time that Midas quit making and carrying them in inventory.

I have never known a muffler for the A to have a number. Where would I look for this number?

I would suspect that the H4L, H0L and H7F are production date codes., w/the 301 being the part #.
