any places to get older Massey plastic cab parts?

[Hersheyfarm]

I have a 4345 and the plastic "cowl" around the steering column is broke. Tried to order through the dealer but they said it not available anymore. wondering if there is an aftermarket avenue for these type of things. Its actually 2 pieces part #3821469m1 and 3821470m1. Never thought they would discontinue the ability to get cab parts.

Got any pics? A lot of plastic parts can be repaired with the right stuff....
