Razz: FTP 24+2 HORSE Final Table, bad 5th street, help.

[Metnut]

I know i spewed some chips here, but im not exactly sure where I'm supposed to let this hand go. I've looked at the hand and I think 6th street is where i should fold, but the pot odds are ridiculous. I'm a little lost on this game, if i should've folded on 5th let me know. I just need some good razz players to tell me how they would've played this so i can improve. I apologize for the format but i tried three different hand converters and none of them work.

Dealt to Metnut [5s Ac 3h Jd 9d] [8c] I think i should've mucked here, but if hes paired up anywhere, or even if he has an 8 i think i have odds. Is this an easy muck?
