[TR] TR3 oil cooler

[Frank Fisher]

thinking of adding an oil cooler to my TR3.
looking at a few different kits.
im quite capable of figuring my own installation.
most appear to screw onto the filter assembly like the modern filter kit.
i have seen some that appear to go between the filter assembly and the block. i 
think they look like they may perform better? yes/no?
was looking in the way back machine and Teriann talked of some ones kit. but 
then i lost the link to your comment and cant find it again. doh!
recommendations?
thanks
Frank
