I dont know if any of you will find this interesting, but It sure helped me out. I have a 67 coupe with a 289. I have the original oil gauge installed and it works, about as well as a factory oil gauge ever worked. So I wanted to have a mechanical gauge to be certain of my psi. But as you know fords only have 1 place to get oil psi from. Many of you put in a Tee and thats just fine, but for 25 bucks I bought a billet aluminum oil filter spacer that has 3, 1/8" ports around it and I installed it today (took about 10 minutes) and hooked my new gauge up to it, it fits great and does the job, now I have 2 more ports available if i wanted to install an oil temp gauge or oil for a supercharger, whatever. I'll see what I can do to get a pic on here.
