Today i finally got around to installing my oil pressure gauge on my 95 D1. My D1 is a distributor car but i run a serp belt motor with an interim front cover that has a hole for a distributor. So i have a crank driven oil pump and a Distributor and my oil cooler lines are blocked off. I was always curious what my oil pressure was with the oil lines blocked off and since i wheel my D1 pretty hard and it spends a lot of time at weird angles. After spending countless hours trying to find adapters i finally decided on breaking open a factory style sensor and trying to adapt it to work since it had the best sealing surface out of anything i could find/make. After breaking the sensor apart it became clear that i could probably just tap it to 1/8 NPT and thread in my adapter. Then with some creative adapters i was able to install a factory sensor as well, so no idiot light. All in all, i think i spent about $30 in parts. Ignoring the thousands i have in tools lol. I took some pictures through the whole process so if anyone wants to see i can post them.
