Fan Shroud Clamp, 2 bolt vs. 1 bolt, 2.4 liter engines

[caproader]

Guys,

When do I use a 2 bolt clamp to secure the 1973 engine fan shroud and when do I use the one bolt version. I have two of each and can not remember what goes where or why. Is it by engine type (T vs S) or did it change on a specific date?

If this issue is discussed on a previous thread, could I ask for assistance in finding the thread.

Thanks, The Original Ludditte

I believe the change from two bolt to one bolt for all models was around March of '73.......

Hope this helps…

Chuck,

Thanks for the help. The COA says the build date for my 73 S with Sporto was 4/16/73. So it looks like I go with the one holer. Of course, when I looked at the 73.5 CIS Targa, I noticed that somewhere along the line it acquired a 2 hole clamp. Just one more project to add to the list. But then it looks like a long winter here in Ohio. 10 degrees and 4 inches of snow tonight and it is still only 15 December.
Thanks again
