42" Pony Deck question..

[Halligan_Pierce]

Does anyone know the difference between DECK ASM-42S and Part #983-05136-0638? I only need to replace the shell, as the spindles, blades, guides and belt are all fairly new. When I put this part number into Troy-Bilt's part search for the deck, both numbers return from the search, but no real description and no picture to compare.
This is for a 2014 Troy-Bilt Pony Model 13WM77KS011.

Thanks in advance.

The part number shows as being the ASM 42s

Well going to need the serial number (plus manufacture date if shown on he serial number tag) and if you have gage wheels or not. This is because the 2014 model had 4 different decks. and they made this the seond or third week in May 2014.
