Fleetwin,
I believe you are saying Do as I say, not as I do IE, The factory used nothing but who back then thought after 20 years they would still be around! 😆 I have never used sealer but why not!! Don’t forget the bottom end tap for the holes too & remove the scrap thread chunks. The antisieze I have used on Corvair & V.W. stuff & still came apart after we blew them up. More like sanded them at Baha!!
