I need a dip stick tube for a 1982 - 307 engine. I had my car into a shop to have all the frost plugs changed. There is still one frost plug the shop did not do. Its the back one on drivers side . The shop had to take the starter out to get at this frost plug , then wanted to remove the engine oil dip stick tube , the shop was sure the dip stick tube would come apart. So i decided to leave that one frost plug until i come up with a dip stick tube . i looked on line before posting this , looks like there are a lot of choices. But thought i would ask on this forum before ordering a dip stick tube . Do i look for an original or reproduction ? if i look for a used one , what engines share the same dip stick tube ? Just want the best fit , do not care what it looks like .
