Bachmann 34 376 63 Thompson 2nd Corridor Maroon Br Hook and Loop Coupler Parts

[Steve-Trains]

Apologies if this has been covered before, but I was unable to locate an answer on these Forum pages, please feel free to direct me if this has been covered elsewhere. I have what I have identified as a Bachmann 34 376 63 Thompson 2nd Corridor Maroon Br Coach. It has Hook and loop couplers, but is missing the hooks. The loops themselves look to be integrated as a part of the molding of the wheel truck/bogie, ie they are not separable from the wheel truck. I have been unable to locate replacements hooks for these wheel trucks, can someone point me in the right direction please?
