This is an interesting thread. Earl's sells oil coolers, and they had so
much trouble with people breaking them they removed all the mounting
tabs. The recomendation was to capture both sides with a "c" channel
with rubber/foam lining. I though this was overkill but did it
on several
motorcycle applications. I never had a problem. These were used with
80+ psi oil and racing apps. (they saw lots of high frequency vibration
and often saw very high G impacts without problem) We all might do
well to look at the way the motorcycle manufacturers mount their
radiators and oil coolers on the motocross bikes. These operate in an
enviroment that mose people would call "abuse" to begin with!

Funny you should mention it.  I have an Earl's cooler sitting around and was
considering mounting it to replace the broken Setrab.  The first thing I did
was cut off the mounting tabs.  It is only about 2/3 the size of the Setrab,
and I eventually decided not to mess with success.  I ordered a replacement
Setrab, but the first thing to go will be the mounting tabs.

I plan to pro-seal some thick alum brackets to the sides, and make the
rubber thicker softer on my mounts, then build up JB weld around the
fittings like Tracy does.

Best not to risk those Earl's coolers. Lots of bad feedback on those
and not just from the rotary guys.
