hook up oil pressure gauge not using sending unit

I am trying to install an oil pressure gauge on my 1991 Acura Integra race car but the moron that I got the car from JB welded the sending unit closed so I can't hook up the gauge there. Is there anywhere else I can hook it up to?

go to ebay and look up an oil filter sandwich adapter it goes between your oil filter and the block and allows up to 2 1/8 npt sending units to be hooked up it cost me 30 bucks heres a link http://cgi.ebay.com/ebaymotors/BLUE-M22-OIL-FILTER-GAUGE-FILTER-SANDWICH-ADAPTER-KIT-1-/230652040821?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1991|Model%3AIntegra&hash=item35b3eed675
