I dispensed with both the clock & the oil temperature gauge, being neither interested in the time when I’m out, nor the fatuously inaccurate temperature figures & replaced them with something I am interested in, oil pressure plus an accurate temperature reading. To adapt these I bought a sandwich plate to go between the oil filter housing & the filter, assuming that the screw adaptors would be compatible, they are not! The closest the kit comes to being correct is the 20mm x 1.5 unit which screws into the filter although not an impressive fit, the internal thread wouldn’t even look at the filter housing. The thread form is 13/16” x 16 tpi & this on a car from the metric era, with no other imperial thread as far as I am aware. Fortunately I picked up a 13/16 tap & ten minutes later I was screwing it all together, the thread disparity between the oil filter & adaptor wasn’t significant enough to be a worry although I fitted a generous amount of PTFE tape to make the fit “more reassuring”. And as Ed China would say, Result.
