It looks like it changed from A to B sometime in the '86 model
year...Mine's definitely the A version. Ken from Vanagain to the rescue. He
had one in stock. I see sort of a cutout in the firewall, where the coolant
tower can be located a couple of inches to the right of where mine is. That
would make sense for the B version as it seems to have 2 90 degree bends,
where the A version has 2 60 degree bends. The idea being that the offset
between the Head and the tower is greater for the B version. Mine is now
patched with silicone X-treme Tape <http://x-tremetape.com> awaiting the
new hose  :)
