93 oil psi gauge sensor thread size

[93fs]

Just about ready to drop in the lq4 and I was planning on using the stock oil psi sensor in a block off plate for the oil cooler. I thought my factory 93 sensor was an 1/8" thread. But from a little reasearch it's looking like its 1/4" they make a block off already tapped for an 1/8" sensor but I can't find one for 1/4", does anyone make these? Or am I best off just buying a normal block off and drilling and tapping it to fit?

did your 93 sensor screw directly into the block?? On the swaps I have completed the there is an adapter between the sensor and the block.. I always use this style adapter so that I re use the stock apater and sensor on my swaps in the stock location behind the intake
