73T Motor #6135251

Hello GA,
The above engine, a 2.4 liter, probably CIS, was removed from the 73T I now own at a place called Auto Doc in Scottdale GA in 1985. (Yep I said 1985). I am looking for the motor. I contacted the business which is now called Summit Auto and they do not have the engine. The man who owned the original business, David Barnes, has passed away and I have no other lead as to where the engine has gone. Anyone there have a good source for the possible location of the motor.
Thank You
