Tom,
Thanks for explaining the origin of the oil cooler, i didn't know! I'm the
seller.
I got the unit from a roadster that crashed in a parking lot, the
accelerator wedged as the driver was spiraling his way up to the next level,
grinding the right side of the roadster completely down. The roadster was
beyond repair and the owner parted it out.
The oil cooler was mounted in front of the radiator, secured with a couple
of nylon tie wraps.
As my roadster will mostikely never see a race track and given that the
weather in the bay area is rather cool, i've decided to part with it. I can
check the size to see how it measures up.
As a side note, I also got a solex setup from that roadster, they are 44's
but with chokes that pull in the other direction. Originally, they must have
been passenger side mounted, don't know what motor/car though. I wonder if
there's a way to convert them back.
