What grade to use

[Denvermike]

The donor 727 trans didn't come with bolts. I can measure for the size and thread count with no trouble. What grade should they be 5 or 8? Thanks for any help.


You might feel old when a teenager in baggy pants and a hoodie holds the door for you.

Grade 8.

LOL, the grade 8's are pennies over the grade 5 bolts. you local ACE hardware or equal store will have them.

 

[moper]

Grade 5.

Sorry!! I am missing the bolts that mount the trans to the engine.

I would go with grade 8. Todays chinese grade 5 bolts are more like an old U.S. grade 1.

Grade 8. You can buy them by the pound at TSC.

Once again Rumble is right on the money here.

If I am ever in a doubt on which bolt, I spend the extra pocket change on the grade 8s.
