I've been caught up dealing with vandalism at my shop for the past few days
and missed the beginning of this thread - so forgive me if I'm missing the
point - but it looked as if the gist was trying to identify the original
fitment of the various fan extensions pictured.
This one is from our store on ebay. It came off of either my own TR3 or one
of our parts cars, all of which are somewhere in the '59-'61 range of years
and all of which had 4 bladed metal fans. I don't have the chassis numbers
handy right now. For comparison to your parts, the dimensions are as follows:
4" long, 3.4" big end dia, and 2.785" small end dia. Stamped on the side is
Hope that helps,
