they are a 9 mm. sears has a set with that size. auto zone does not have that size.
Have you checked to see if Autozone.com has that info? They have many repair manuals online for free!
Lowe's has a set of Kobalt keys with a T-handle for like $12. Sears and autozone sets are very full sets and are over $20.
It is a 9mm allen, I finally found a set of Allen wrenches that included a 9mm at Home Depot for around $11, Sears did not have one, nor did O'Rielly's
These are 9mm hex bolts. Had to search for a 9mm, finally saw one at Lowes of all places, bought a set of allen wrenches. Works well.
