I'm pondering putting either a slightly (or much) larger water/oil
heat exchanger from a PD or V6 on my beast to take the edge off my
temps.
I've found a couple of small, pretty much rectangular oil cooler units
that would fit vertically on to the D-Pillar hole vacated by the WBX
airbox and idle control unit.
Tencentlife on The Samba has a kit that stashes a slightly larger unit
at an angle in the same space. Nicely done set up.
Holler if you want to compare notes.
