I'm looking for a working oil pressure gauge for my 68. Currently I have an aftermarket one in the upper left hole which uses a tube and leaks and reads in kg/cm2 as well as psig. I've looked in all the catalogs I buy parts from and no one seems to sell them. One odd thing is that the restoration book I have indicates that I should have oil temperature combined with the ammeter in the right large gauge and a fuel gauge in the upper left hole. What I have is fuel and ammeter in the large right gauge and the incorrect oil pressure in the upper left. I'd appreciate it if someone could give me a source for a gauge and maybe shed some light on the gauge confusion. Thanks

 

Not sure if this will help but I find the best bet for locating obsolete parts for my 65 coupe daily driver is Ebay. There are a lot of mustang parts on there and if it's not there today keep checking every 2 or 3 days and it will probably turn up within a week to 10 days on average. Alot of mustang suppliers & people parting out cars will put stuff on there that is hard to find otherwise.
