ive done it on the 88 and with the headers its farther down and easy to reach. im trying to do it on the Z28 but its got stock manifolds and its way up high, just above the collector. a 7/8in wrench fits on it from underneath but there is barely enough room to turn it and it feels like its gettin stripped. ive soaked it in stuff, ive even heated it up to 120* like the instructions say. anyone know a trick????
