1984 Mercury Lynx
I believe they are .621
patatocake is probably right, I came up with similar, Outside Diameter (in): 0.675 in. Inside Diameter (in): 0.516 in. Height (in): 0.650 in. but for small block V8. But when I looked for engines in '84 Mercury Lynx it has a 1.9L? Is that what you have?
They have a wide selection of dowels, and better than stock. Stock are a rolled piece of steel with a gap. Summit racing sells solid steel dowels
