Heater box-to-plenum "j" hook/bolt, '71 Challenger

[hemi68charger]

Hello all..
Just discovered that the 'J' hook/bolt that's used to help support the heater box for my friend's '71 Challenger R/T is missing. It's the support hook that fits over the cool-air plenum on the passenger side and connects to the heater box. Anyone out there with that hook support fastener or now where I can get a reproduction if it's made?

Thanks.

They're out there on E pray every once in a while. I just bought mine last night on it.
Hang in there and one will show up...if you don't find one.
