They had to remove the Antique Cars because the main entrance was relocated to that area. Originally they were going to place it under the Log Flume on the peninsula of land which supports part of the ride but found that not to be the best choice because water often overflowed from the trough above.  

How come Great Adventure couldn’t leave the antique cars where they were 😞

While I do not know this for sure, I believe he may have been tasked with creating the scale models for all of the Six Flags parks new attractions in 1978, which was his first and last season with the company.
