B&M or Hayden cooler?
is better.
I picked up a pair of the "Perma-Cool" frame-rail types
(long and skinny, with mounting feet) which I plan to
use for a different install scheme, get the cooler off
the condenser / radiator "stack" so it's less obstructed.
They have less area than the max-size brick types
though.

The exception is a frame rail cooler which is a different shape and designed to be mounted in a different location. Capacitywise, they are fine for smaller converters (no more than 3500) as the 24" is rated for 15,000lbs GVW. Even though it is rated for 15000 GVW, I notice that it has tube length than a typical fin type cooler of similar rating. A frame rail cooler and a good deep pan would work well for those that do not want to block the radiator or use the "Dope" method of mounting.
