Fuel pump block off plate

Will a fuel pump block off plate from a V8 fit on a slant six? Looked at different suppliers and all are for BB and SB V8s
I Put on an electric fuel pump due to fuel delivery issues but the old mech fuel pump is still mounted to the engine, I know it will eventually blow it's oats and leave me with a puddle of oil under it

Sorry if this has been asked before, went back several pages and didn't see anything
