So Mr. George Whitaker Sr. said in writing that there was a hole in the windshield but never wanted anyone to know that he said that until he was dead and gone. I find that to be a very smart move on Mr. Whitaker's part . It game him more time to live, unlike Dorothy Kilgallen who left life a little earlier!
Read what Pam McElwain Brown, who knows more about ss100x than anyone else, has written about Whitaker and the limo. She found that there was no "repair garage" in Building B in '63, contra Whitaker's claims. She also notes that the limo had a standard '61 Continental windshield from the day it rolled off the line at Wixom until it was rebuilt after the assassination. It wasn't "made special" as Whitaker would have you believe, and a replacement didn't need to be custom-made, either. She's noted that the limo was built in Wixom, Michigan, had its chassis stretched at the Ford Experimental Garage at the Ford Proving Ground, and all the extra coachwork and interior were custom-made to fit by Hess and Eisenhardt in Ohio. Ford generally, and River Rouge in particular, didn't have the expertise to replace the interior; that's why it had been farmed out to H&E in the first place. There are too many problems with Whitaker's story to take it seriously, and that's why he didn't want to see it public in the first place. He simply didn't want to live to eat his words.
