yeah Sonny do your research before you go in deep with modifications, I spend half my time here just waiting on parts to arrive via mail or UPS/Fedex. There's only one hyd.supplier closeby and they are high as hell on anything there,they mostly cater to businesses and large contractors..they wanted 18.75 for each adapter fitting to refit the cylinders to SAE O-ring. The new 1/2" NPT hoses were $25each from Surplus Center, so that was an easier fix.
