79 911sc seat mounts / brackets

[mflinn11]

I have a 79 911sc and at some point along the way the factory seats were replaced and the factory mounts and rails along with them. Im looking to put factory seats back in and Im having a hard time finding replacement mounts and brackets and was curious what years that specific bracket / mounts were used (or what other models? 944?)? Or if anyone has any recommendations on an after market bracket that will hold a factory seats? Also, if anyone has a set of mounts that will work for me I will obviously consider. Thanks for the info
