The coolant cross over manifold has like a nipple on the bottom that I inserted into the water pump ... the nipple is corroded and has partially broken off is this replacable or do i need the entire cross over header/pipe

Thanks Frank

Years ago I had the nipple on my 63's crossover repaired because it was also corroded to the point of not sealing.  I took the crossover to a good machine shop. They turned down the nipple a little and pressed a brass bushing on it to bring it back to spec. I used 2 orings to make sure it sealed in the water pump.

Ditto on the 2 O Rings. I've done this many times and it really helps avoid leaks and makes installation more "forgiving" .  Joe Gibeault
