Passenger seat latch

[NJKelly]

Hi all, looking for a picture or diagram showing where the hold down latch is installed on the passenger side for a 71 Blazer. I went through the 67 to 72 Factory assembly manual page by page and could not find anything. If any one has a picture maybe with some measurements I appreciate it. I thought I might just put the seat in and line up front holes and then where were the latch works in the back drill some holes. It seems metal was replaced back there and there are no holes now. Thanks.
