For sale are three sets of late 72-76 type tubes with the larger big end.
This is a great way to to the push rod seal replacement so you do not have to clean the old set. No fun.
Four sets pictured. Have a fifth set and two more sets without O rings.
Minor dents on some and some pocked area from rust.
Asking $65 a set shipped in the U.S. New tubes are about $6-!2 each and a set of Viton O rings runs about $20.
