328 steering rack pinion seal

Does anyone have a source for this seal. Search speaks of a honda motorcycle seal but couldn't find anything. I have rebuilt the rack making the paper gasket from gasket material and fabing the right side bushing out of 1" starboard using the "clamshell" methood of installing to avoid removing rod. I warmed the bushing with propane torch so as not to split the bushing in two while slipping it over rack shaft. Small set screw seems to be holding bushing just fine. The action is better than new...no more clunk over bumps and shimmy at high speeds.
