NSGRN: Yes there is a kit Derale #16749 that is adjustable 150 to 240 Degrees. It has a 3/8 NPT sensor and a separate electronics/relay box where the adjustment is made. I've seen this on a few websites and interestingly the length of the sensor seems to be different in each photo, so not sure if a suitable replacement.
Bluebird428: Looks very tidy under that hood. Same layout as mine with similar (SPAL?) switch on left and gauge sensor on right... some advice on other websites says it should be the opposite but I haven't found any recommendations from Edelbrock.
I now also know where the washer bottle mounts, missing on mine.
