[TR] TR6 Cooling Fan on a TR4A

[Jim Henningsen]

I saw a picture somewhere that had a red TR6 cooling fan on a TR4A.  I would
like to swap out my original four blade metal and have a spare TR6 red
blade.  Anyone done this? Won't know what I have there for mounting until I
pull the radiator to get recored.  I do not have a spare yellow blade fan.
Just curious what wisdom folks have learned on the list.
Thanks,
