Hi there, thanks for taking the time to look. I need a little help. It's fairly straight-forward, just cant seem to find the info I need.

I am dropping a 350 back into my engine bay. I pulled the old engine mounts out to replace them, and along the way seemed to have "misplaced" them.

Does anybody happen to know what size bolts and other hardware i need? I am in need of the fasteners that hold the mounts to the frame, and the ones to hold the engine to the mounts.

 

Mounts to frame = 3/8-16 x 1" + flanged nuts; mounts to block = 3/8"-16 x ¾"

All common parts store items

 

Thank you very much. That should get me off the couch for the day.

 

Also, would you happen to know the bolt size tof the long bolt that holds both mount together?

 

Should be a 5/8" bolt but is also a special bolt. Although you could use a generic bolt, you should get the proper bolts for that.

 

Thanks for that. I appreciate all the help I can get from you guys.

 

I know the bolt head and nut are 2 different sizes. Another of the 80's-90's General's inexplicable ideas.

 

My mistake, the bolt should be 7/16" not 5/8" All 7/16" bolts have a 5/8" head and the 7/16" nuts are 11/16"

 

Hi Guys, greetings from New Zealand 🇳🇿 . Im in the current situation of needing to replace all of my engine mounts in place. I saw Eric the car guy on YouTube using a long handled swivel head ratchet ring spanner to get up to the nuts inside the crossmember. This looks like a great option to me! Can anyone tell me what size ring spanner I need for this job please?

 

You don't need a ring spanner. You'll need a 15mm swivel socket, and a 1/4" drive extension with an adapter for a 3/8" drive socket & ratchet.
Put a piece of electrical tape over the nuts before inserting them into the socket. That way, they won't get dropped down into the k-member...

 

Thanks for that

I have already completed the drivers side & just about done the passengers side. I did need a skinny extension for the passengers side though.

cheers for the help
